Jyotisha Web Design System

This file adapts the full visual analysis in CLAUDE_DESIGN.md to the shipped Jyotisha application. CLAUDE_DESIGN.md remains the upstream reference; this file is the implementation contract.

1. Atmosphere & Identity

Jyotisha feels like a private reading room: warm, editorial, grounded, and quiet enough for reflective conversation. The signature is a pale parchment canvas, translucent warm-gray navigation, fine neutral hairlines, and restrained deep-brown accents. Serif display type gives astrological guidance the gravity of a considered essay rather than a generic chatbot.

2. Color

Palette

Role	Token	Value	Usage
Canvas	--color-canvas	#fbfaf7	Main reading surface, inputs, light controls
Page floor	--color-canvas-soft	#f3f2ee	App background and quiet secondary bands
Warm surface	--color-canvas-muted	#ebe9e3	Cards, user messages, table headings
Strong neutral	--color-canvas-strong	#e1ded6	Pressed and emphasized neutral surfaces
Sidebar glass	--color-sidebar	rgba(235, 233, 227, .86)	Desktop navigation only
Sidebar solid	--color-sidebar-solid	#ebe9e3	Mobile drawer, and any reduced-transparency surface
Selected surface	--color-selected	rgba(255, 255, 255, .62)	Current navigation and raised light rows
Ink	--color-ink	#1d1d1f	Headlines and primary text
Body	--color-ink-strong	#32322f	Strong body copy
Secondary text	--color-ink-secondary	#5f5f59	Supporting copy and labels, section headings
Tertiary text	--color-ink-tertiary	#6a6963	Hints, metadata, empty-state copy
Primary action	--color-action	#85432f	High-signal links, rings, and compact actions
Primary soft	--color-action-soft	#f4e8e2	Editorial emphasis without a dark block
Primary active	--color-action-hover	#6f3627	Hover and pressed action
Dark punctuation	--color-surface-dark	#1d1d1f	Compact primary buttons and user-authored emphasis only
On dark	--color-on-dark	#fbfaf7	Text on compact dark controls
Hairline	--color-border	#d8d6cf	Default separators and controls
Strong hairline	--color-border-strong	#b8b5ad	Inputs and higher-contrast dividers
Success	--color-success	#28633e	Available and completed states
Warning	--color-warning	#b07b22	Caution states
Error	--color-danger	#9a2f2f	Errors and destructive actions
Accessible focus	--color-focus	#85432f	Keyboard focus and input focus

The personal report reuses the product palette. --report-* tokens exist so print can pin a light sheet independently of the screen theme; they are the canvas, hairline, and action colors, not a second visual identity. Nothing outside .personal-report-* and .report-center-* may use them.

Role	Token	Value	Usage
Report paper	--report-paper	#fbfaf7	Same as --color-canvas; the reading sheet
Report rule	--report-rule	#d8d6cf	Same as --color-border; rules inside the sheet
Report accent	--report-accent	#85432f	Same as --color-action; scarce evidence links

Rules: neutrals stay warm; the action color is scarce; roughly ninety percent of the interface remains light. Dark ink is punctuation, never a page-scale surface. No raw color may appear in UI styles outside these tokens and their documented alpha mixes.

Where the action color appears

Scarce is a budget, not zero. The sidebar spends it in exactly three places, and a fourth needs a reason:

1. 新建对话 — the one high-signal action in the nav, as tinted text and icon on a transparent row (--color-action, deepening to --color-action-hover). Never a filled block: a full-width terracotta surface would break the ninety-percent-light rule.
2. The 2px bar on the active session (--sidebar-ring).
3. The profile initial's circle (--color-action), which only renders when the account has no uploaded avatar.

2 and 3 both disappear on a new account with an avatar — no sessions, no initial — which is how the sidebar ended up with no accent pixel at all. Item 1 is what guarantees the nav still has a visual anchor in that state. 我的报告 and every section label stay neutral on purpose; giving them color too would flatten the hierarchy the accent exists to create.

The glass surface assumes a light backdrop. The mobile drawer floats above the scrim instead, so the translucency darkened it to #E3E1DC and flattened the warmth; the drawer takes --color-sidebar-solid and drops backdrop-filter.

Hierarchy inside the nav comes from ink rank, not hue: section headings sit on --color-ink-secondary, their body and empty-state copy on --color-ink-tertiary. Both used to share tertiary, which is why the nav read as one flat grey. Empty sections name the next step in that same neutral copy rather than adding a second tinted call to action.

Dark theme

The dark theme is a role-preserving restatement of the palette, not an inversion. Every themeable token is redefined; frontend/tests/dark-theme-contract.test.ts fails if one is missed.

Three states, the standard pattern: with no attribute the page follows the OS through prefers-color-scheme; data-theme="dark" or data-theme="light" on the root element pins a choice and wins in both directions. Plain CSS cannot share a declaration list, so the dark palette is written twice — once inside the media query, once under the attribute — and a contract test asserts the two copies stay identical.

Role	Light	Dark	Why it is not an inversion
Page floor	#f3f2ee	#1a1a19	On light, raised surfaces step down in lightness; on dark they step up. The floor is the darkest surface in dark mode, the second-lightest in light mode.
Reading surface	#fbfaf7	#262624	Warm, never neutral black. A cool grey would change the product's identity rather than its brightness.
Warm card	#ebe9e3	#30302d	One step above the reading surface in both themes, by opposite directions.
Primary action	#85432f	#d78064	The clay hue is kept and lifted. #85432f is 2.1:1 on #262624 — unreadable.
Action hover	#6f3627	#e59273	Hover darkens on light and lightens on dark.
Dark punctuation	#1d1d1f	#f2f0ea	A dark block on a light page becomes a light block on a dark page; the token name describes the light-theme value, the role is "highest-contrast block".
Semantic hues	#9a2f2f / #28633e / #b07b22	#e08573 / #74b189 / #d8a758	Lifted for contrast; their -muted pairs stop being pale washes and become dark tints of the same hue.
Scrim	rgba(29,29,31,.34)	rgba(0,0,0,.58)	A scrim has to darken a surface that is already dark.
Shadow	low alpha	~5× alpha	Without a light ground to fall on, a soft shadow registers as nothing.

Contrast is asserted, not assumed: eight inks (ink, ink-strong, ink-secondary, ink-tertiary, action, danger, success, warning) must all clear 4.5:1 against four dark surfaces (canvas-soft, canvas, canvas-muted, sidebar-solid). The four neutral surfaces must increase in lightness in floor → canvas → muted → strong order. Adding a text or surface token means adding it to that 32-pair matrix; checking only the reading surface is not enough.

Surfaces that do not follow the theme, on purpose:

• The payment QR keeps literal white in both themes. Scanners need the light modules to actually be light.
• @media print keeps white paper.
• The admin is antd + Refine and stays light. Re-skinning admin.css alone would give a dark shell around light antd components, which reads as broken; doing it properly means switching antd to theme.darkAlgorithm as well, and that is a separate change.

The control is a radio group inside the account menu (avatar → 外观), so it keeps menu semantics: arrow keys reach it and the current choice is announced. Three options, matching the three states — 浅色, 深色, 跟随系统. Picking one does not close the menu, so the change is visible where it was made.

"跟随系统" removes data-theme rather than writing a third value; the media query has nothing to match otherwise. The choice is stored under jyotisha-theme and re-applied by a synchronous script at the top of <head> — it must not be deferred, or every load flashes the other theme before hydration. Blocked storage degrades to following the OS. The preference is per-device, not per-account, and is read through an external store so a change in one tab reaches the others.

3. Typography

Font stacks

• Display: "Tiempos Headline", "Songti SC", "STSong", "Noto Serif CJK SC", Georgia, serif. The licensed Copernicus/Tiempos files are unavailable; the Chinese Song serif stack is the declared production substitute.
• Body/UI: StyreneB, var(--font-inter, Inter), -apple-system, BlinkMacSystemFont, "Segoe UI", "PingFang SC", "Microsoft YaHei", sans-serif. Inter is loaded with next/font/local from src/app/fonts/InterVariable-latin.woff2 (display: "swap", CSS variable --font-inter) so Windows/Linux no longer silently fall back past a never-requested Inter, and image builds do not call fonts.googleapis.com. Tiempos Headline remains unloaded; the Songti stack is still the declared production substitute.
• Code/data: "JetBrains Mono", "SFMono-Regular", Consolas, monospace, exposed as --font-mono.
• Root boundary pages (error.tsx, not-found.tsx, forbidden.tsx, global-error.tsx) sit in the shared root layout segment and must not import globals.css — importing it would drag the chat stylesheet onto every admin route. They therefore cannot read --font-mono or any token, and inline their own values: a system stack for body text and ui-monospace, SFMono-Regular, Menlo, monospace for code. Keep those literals in step with the stacks above by hand.

Scale

Token	Size	Weight	Line height	Tracking	Usage
--type-display-lg	48px	400	1.1	-1px	Desktop page titles
--type-display-md	36px	400	1.15	-.5px	Dialog and mobile page titles
--type-display-sm	28px	400	1.2	-.3px	Section titles
--type-title-lg	22px	500	1.3	0	Prominent UI titles
--type-title-md	18px	500	1.4	0	Card and message headings
--type-title-sm	16px	500	1.4	0	List titles
--type-body-md	16px	400	1.55	0	Default reading text
--type-body-sm	14px	400	1.55	0	Compact UI text
--type-caption	13px	500	1.4	0	Labels and metadata
--type-overline	12px	500	1.4	1.5px	Eyebrows and badges

Display headings use the serif stack at weight 400. Body copy never drops below 14px; 12–13px is reserved for short labels and metadata. No product UI text is smaller than --type-overline (12px). Product UI uses three font weights: 400 (display and body), 500 (UI titles, labels, buttons), and 600 (emphasis only). CJK text uses text-wrap: pretty; display text uses text-wrap: balance.

One documented exception: the thinking text inside a timeline step (.consultation-run-timeline__thinking) and the fallback thinking trace (.message-thinking-body) render at 13px. They are working notes shown on request inside a collapsed row, not reading copy; the answer itself never inherits that size.

4. Spacing & Layout

The base unit is 4px. Tokens are --space-1: 4px, --space-2: 8px, --space-3: 12px, --space-4: 16px, --space-5: 20px, --space-6: 24px, --space-8: 32px, --space-10: 40px, --space-12: 48px, --space-16: 64px, and --space-24: 96px.

Radii have two visual steps. Controls use 8px (--radius-md; --radius-xs and --radius-sm alias that value). Cards and sheets use 12px (--radius-lg; --radius-xl aliases it). Circles stay 50%; pills stay 999px.

• Chat reading width: 760px for the welcome/composer and 900px for long answers. Both chat surfaces share the 900px transcript width; the rectification session no longer narrows it to 720px.
• Admin content width: 1200px, centered.
• Desktop shell: 288px sidebar plus flexible reading panel.
• Layout breakpoints: mobile below 768px, tablet 768–1023px, desktop 1024px and above. These three decide the shell — sidebar mode, grid columns, drawer versus rail. CSS @media width cuts must follow sidebarViewportForWidth in frontend/src/lib/sidebar-state.ts (768 / 1024), not the other way around. The allowlist lives as a comment at the top of globals.css and is locked by frontend/tests/viewport-breakpoint-contract.test.ts.
• Allowed @media widths: 480 (small phone), 640/641 (content grids: membership, rectification candidates, intake card), 767/768 (mobile/tablet), 860 (report TOC, content width of the third column), 1023/1024 (tablet/desktop). Do not add a new width without updating that list and the contract test in the same change.
• All full-height surfaces use 100dvh. Touch targets: on a coarse pointer the hit is 44×44; the visual control may stay smaller. Message-action icons stay 26×26; a fine pointer keeps the 27×34 overlay, a coarse pointer opens gap and bottom margin to 20px so a 44×44 overlay does not eat the next button or the follow-up pills. Locked by frontend/tests/touch-target-contract.test.ts.

5. Components

Brand mark

• Structure: image-backed mark plus serif wordmark.
• Variants: light canvas, dark sidebar.
• States: static; never animated.
• Accessibility: decorative image is hidden when adjacent text names the product.

Button

• Implementation: report surfaces and the billing pane use @/components/ui/button. Login, onboarding, and birth-time dialogs still use .button-primary / .button-secondary, which share the same 44px height, 8px radius, and action tokens. Those CSS classes stay until those surfaces can move without growing page.tsx.
• Variants: ink primary, cream secondary, text, circular icon, deep-brown emphasis.
• Spacing: 44px minimum height; radii 8px for standard and full radius for icon-only.
• States: default, hover, active, focus-visible, disabled, loading.
• Motion: 120ms transform/color; active translates by 1px or scales to .98.

Input and composer

• Structure: warm canvas field, hairline, typed value, optional icon action.
• States: default, hover, focus with deep-brown ring, disabled only for structural reasons (readonly, session loading, onboarding, the other surface open), invalid. Generating does not disable the textarea; the send control becomes stop.
• Queue: one pending card (.composer-queue) sits above the field while an answer is in flight. Copy: “已排队，回答结束后发出”, plus the text and a 44px “撤回”. A second Enter appends to the same card with a newline. Successful settlement sends it; stop, failure, or recovery puts the text back in the field. The send button is disabled while a card is waiting. No spinner.
• Accessibility: persistent label where practical; composer has an explicit accessible label.
• One composer: the rectification surface renders the same ChatComposer as the main chat; there is no second composer. A surface that owns its own draft passes it as value; the main chat reads the draft store. Both count down from the same 500-character ceiling through CharacterRemaining.

Jump to latest

• Structure: one pill button (JumpToLatestButton) with a down arrow and the label “跳到最新”, shared by both chat surfaces.
• Placement: hangs off the composer wrap's top edge (.jump-to-latest, absolute, bottom: 100%) so it never reflows the transcript or the composer.
• Visibility: shown when the reader is not anchored — more than 96px from the bottom after scrolling up — and hidden again once they return or press it. Sending a question re-anchors.
• Surface: canvas fill, hairline border, --shadow-elevated; hover uses the warm card surface. No utility-class shadows.
• Accessibility: a real button in document order with a visible label matching its accessible name, 44px target, and the focus ring; the icon is decorative.

Ayanamsa preference

The self-profile editor in 星盘资料 (ChartLibraryPanel) owns the ayanamsa radios. Personal 个人资料 stays account basics only.

• Structure: four 44px stacked radios reused from .theme-preference-option, plus a caption under the group. Raman is marked 默认. Each option has a one-line description; selected rows show the same Check as the theme panel.
• Values: raman (default) / lahiri / kp / true_pushya. Copy lives in frontend/src/lib/ayanamsa.ts.
• Hint: “之后的咨询、报告、星盘库和每日星语会按新岁差算。生时校正目前仍固定按 Raman，之后的版本才会跟着这项设置走。”
• Placement: after ProfileFields on the self-profile form only. Not on other-chart save, not on page.tsx.
• States: default, hover, selected (aria-checked only), keyboard focus. Switching does not clear a confirmed birth minute.

Rectification surface

The birth-time rectification session is the consultation transcript plus a house board; questions live inside the assistant message that asked them. It shares every waiting vocabulary with the consultation surface; nothing here spins or says "loading" after the reveal.

• Reveal: the surface mounts once per session/Case binding. Opening a Case (homepage card, sidebar row, deep link or refresh) reads the turns and the snapshot in one Case request before the switch, under the same 4-second budget as the home reveal (RECTIFICATION_OPEN_HYDRATE_TIMEOUT_MS is BOOTSTRAP_PREPARE_TIMEOUT_MS); a session selected at bootstrap is hydrated during the prepare phase. The entry shows a static note meanwhile (card footer “正在打开…”, sidebar row “打开中”, cursor: progress) and the previous view stays put. Turns and snapshot are initial state; anything that arrives later is a prop or state update, never a remount. A late or failed read still reveals, with the composer notice “校正记录没有完全加载，可以继续”.
• States — what the transcript's trailing entry and the composer show:

State	Trailing entry	Composer
opening	live row “正在读取你的出生资料，准备第一个问题…”, then tool labels	enabled (typing queues), stop visible
empty	“这段校正还没有开始。” and one primary action “开始提问”	enabled
question-live	the asking message carries the embedded card or the spoken stem. An active spoken or choice focus without asked_turn_id hangs on the last assistant message, same avatar column	enabled, placeholder points at the card
question-gap, persisted question	only when no assistant message can carry the prompt; a host question row (data-testid="persisted-question")	enabled, placeholder “请回答上面的问题…”
question-gap, retries left	one timeline live row “正在准备下一个问题…”, refetching on a 2s timer up to two retries	enabled
question-gap, retries spent	“没有拿到下一个问题。” and a 44px “接着问”	enabled
question-gap, collect waiting	no “没有拿到下一个问题”; the last assistant line already has the precise gap	enabled, placeholder “再说一件带年月的事”
question-gap, delivered	no current question, or the current question is a dead choice card, and the session already delivered a range (completed_with_range / provisional_range / adopt outcomes, or tied_first); range card or range line plus an exit note. Never “没有拿到下一个问题。”	enabled
verified_idle	one closing line postAdoptVerifyDone under the still-visible range card (same assistant column); no spinner, no reload	enabled
choice-pending	the answered card (data-selected fill, a top row “正在记录…”) and the same live row from “正在记录本次选择…” through the follow-up turn	enabled (typing queues), stop visible
candidates	one range-delivery card titled “目前范围 …（对照了 N 件经历）”, a caption under the title that only names still-open lines; when the top two relative likelihoods are within 3 points and collect lines are closed, a body-size invite to add one more event of any kind, asking for an exact day first then falling back to year-month (never “能问的都问完了”). The invite’s subject matches the remaining count in the same paragraph: 2 → “这两分钟”, more than 2 → “这几个候选”, unknown → omit that clause. Optional “再答两道参考题微调排序” only when unused D9/D10 remain; if those were already asked and the top two are still within one point, a line “这两分钟按现有信息分不开，参考题已经用过.”; then up to three compare columns (highest posterior first; “更像这个” adopts); a closed “查看验证报告” fold. On a normal convergence, unused style questions are asked before this card. Exhausted and closed-ceiling exits still deliver the card if a style question cannot be rendered.	enabled
adopting	“正在采用 HH:MM…” through the follow-up turn	enabled (typing queues), stop visible
confirmed	“已确认校正时间：HH:MM”	enabled
readonly	“该校正已结束，只能查看历史。” and “再次校正”	disabled
stopped	the row settles with what streamed; a grey caption “已停止，已生成的内容保留；本次不会扣点。” under the body, never role="alert"	enabled

• Rules: a follow-up turn continues on the live row already in place; busy never drops in the middle of a chain. No copy may ask the reader to wait for the server; a gap is a live row with retries, then a repair button. A hydration that timed out is the same gap. A 402 shows “校正点数不足，正在前往兑换…” for 600ms before the page leaves.
• Board: before any candidate exists the header clock shows the declared birth minute and the body names it by source — “出生记录时间 HH:MM”, “你填的大概时间 HH:MM”, or “你给的时间段” — then “回答几个问题后，这里会显示宫位随时间的变化.”; the column narrows to minmax(16rem, 18rem) (is-board-empty) and widens once a result arrives. No house table is invented for the declared time; the snapshot API does not provide one. The range card may add a caption comparing the declared clock to the current range (“与你填的大概时间相差 N 分钟”, or a hospital-record offset with no preference).
• Accessibility: the sidebar opening note sets aria-busy; the live row is the timeline row (role="status" shimmer label); the repair and start actions are real 44px buttons.

Birth time intake

• Structure: birth date, then three radio rows for “你对这个时间有多确定”——医院记录精确到分钟、家人记得大概时间、只知道时段或完全不知道。家人那档再给四个范围按钮（差不多准 / 前后半小时 / 前后一小时 / 前后两小时 = ±15/30/60/120）。存量 family_exact 档案显示成「差不多准」。之后只露出该档需要的钟点、时段或线索字段。
• Surface: choice rows use the warm canvas and hairline system; the selected row uses --color-action-soft with a deep-brown border, never a dark promotional card.
• States: no source selected, source selected, source-specific details incomplete, ready to continue, assessing, rectifying, candidate saved, confirmed.
• Copy: labels describe what the user actually knows. “完全不清楚” starts rectification from remembered events and compares declared periods before any minute grid; it does not defer correction. Candidate results explicitly distinguish a reported time, a candidate range, and an active chart time.
• Accessibility: native radio inputs remain focusable, every conditional field has a persistent label, status text uses live regions, and the complete flow is keyboard operable.
• Motion: source-dependent fields enter with the existing 180ms opacity/vertical reveal; reduced-motion removes the translation.
• Life-event evidence: after deterministic questionnaire completion, render three structured event rows by default and allow up to six. Each row uses a domain select, a precision select, and a matching year/month/day control; free-form descriptions are not part of scoring.
• Candidate result: keep the reported range, candidate interval, and active-time status visually separate. Delivery shows one range card: title “目前范围 HH:MM–HH:MM（对照了 N 件经历）”, a caption “还能再收窄：如果记得 …” under the title while collect lines remain open, up to three compare columns (time, relative likelihood, D9/D10/nakshatra traits, event-fit counts, next-12-month windows, “更像这个”), and the representative-minute boundary. When the top two columns are within 3 percentage points and the seven collect lines are closed, the card body (not the caption) invites one more dated event of any kind, with examples outside those lines. Collect copy “现在还剩 HH:MM–HH:MM 里 N 个候选” uses the same credible_range as the timeline “目前范围”, not the first/last active candidate minute. An eight-method report sits in a closed <details> fold. Support numbers stay on the house board. Low confidence keeps evidence editing open; medium offers save or add evidence; high uses a separate confirmation action and never labels a column as the true birth time.
• Evidence accessibility: every row keeps visible labels, validation errors use live regions, add/remove controls retain 44px targets, and scoring/confirmation loading states disable duplicate submission without hiding the existing evidence.
• One-question guide: the guided journey renders only the persisted nextAction and one server-selected question. A deterministic question is visible immediately; Agent wording may replace it without changing the question identity, domain, precision request, progress, or permissions. The composer explicitly permits an approximate year. Spoken collect does not render skip chips; typing 「没有」 still declines the domain and 「记不清」 still skips it. Stop on spoken collect is not a composer button: CHOICE_STOP_LABEL (“先这样，先看当前范围”) stays on choice cards, and generating turns keep “停止回答”. The readonly range line is a status sentence, not a stop control. Discriminator cards fold “为什么问这题” under the stem. Hovering or selecting an option does not reveal an answer_impact time line. The method sentence (vargaSentence) lives in the expanded activity timeline, not in the spoken bubble. The composer has no rectification-step-state status sentence and no rectification-composer-meta.
• Draft review: natural-language answers become one inline review card. The evidence domain is read-only and uses its Chinese label; precision controls which exact year, month, or day input is available. Incomplete drafts keep edit and skip paths visible, while confirmation is disabled until the structured date is valid. Status and errors use polite or assertive live regions without clearing the persisted journey.
• Scoring and retry: score_pending is a quiet progress surface with cancellable bounded polling and no manual compare control. retry_scoring preserves the confirmed evidence and exposes one explicit retry action. Refresh and device changes resume from the persisted action rather than inferring progress from copy.
• Guided candidate states: low confidence presents the saved candidate range and either another evidence question or a safe finish; medium confidence can save the range but never apply a representative minute; high confidence names both “候选时间” and “当前排盘使用时间” before explicit confirmation; ready states that the current chart time changed while the original report remains preserved. No state calls a candidate the true birth minute.
• Guided responsive/accessibility contract: body copy remains at least 14px, labels at least 12px, and all controls at least 44px. Focus is always visible, the composer is keyboard operable, semantic Chinese phrases remain together at 390px, and reduced-motion removes entrance translation while retaining state changes.

Birth place picker

• Composition: three cascading Base UI Selects — province, city, district — over the bundled China administrative dataset. There is no free-text search and no overseas provider in this surface.
• Level collapsing: a level that offers no choice is not rendered. Municipalities and special administrative regions skip the repeated city level; prefecture cities without districts complete at the city; a province with neither lower level completes at the province.
• Unsure escape hatch: any city that has districts leads its district list with “不确定，用市区中心”, so browsing never dead-ends. A stored empty district resumes as that choice.
• Precision copy: the picker states that county-level precision is enough for a chart, so a village or township birth is not treated as missing data.
• Value: administrative codes, the node centre coordinate, and the IANA zone are all persisted. Coordinates come from the dataset; the zone is resolved once per chosen place through the chart engine rather than per keystroke.
• States: nothing chosen, partially chosen, resolving the zone, resolved, and zone service unavailable with an explicit retry. An unresolved zone is never reported upward as a usable birth place.
• Saved profiles: mounting an already-saved place neither refetches nor reports a change, so opening the profile dialog cannot look like a location edit. Changing the birth date does invalidate the stored offset and resolves the zone again.
• Accessibility: every level keeps a visible label, an explicit trigger name, and the 44px target from the select recipe; status text uses a polite live region.

Birth date picker

• Composition: shadcn outline Button trigger, Base UI Popover, and a single-select React DayPicker Calendar.
• Range: local dates from 1900-01-01 through today; future dates are disabled. Month and year dropdowns provide direct navigation, with newest years first.
• Value: display Chinese long dates while emitting the existing YYYY-MM-DD profile value without UTC conversion.
• States: empty, open, selected, focus-visible, disabled confirmed profile, and unavailable date.
• Accessibility: visible label, explicit trigger naming, 44px targets, keyboard calendar navigation, focus return, and collision-safe popup positioning.

Model selector

• Structure: a compact text trigger sits below the composer and opens an upward popover aligned to its left edge. The trigger shows only the active model name; each option shows only its model name and radio selection state.
• Width: the popover is capped at 180px with viewport collision protection.
• Surface: canvas trigger with no card treatment; the popover uses the elevated canvas recipe, warm hairlines, and one selected-surface row. The action color is reserved for the selected indicator and focus ring.
• States: closed, open, hover, focus-visible, selected, disabled, and unavailable catalog. Selecting a model closes the popover and only affects later messages in the current conversation.
• Accessibility: the trigger and every option meet the 44px touch target; options are a native radio group, with a small roving-focus fallback so Tab, arrow keys, Space, and screen readers consistently expose the selected model inside the popover.
• Motion: the popup enters over 120ms with opacity and a 4px vertical translation; reduced-motion removes the translation.

Navigation item

• Structure: title, optional subtitle for another person's chart, current-state marker.
• States: default, hover, current, focus, disabled.
• Hierarchy: section labels stay tertiary; session titles and primary actions use ink so history rows do not collapse into the same gray as “收藏对话 / 历史对话”. History groups use the overline token for “今天 / 昨天 / 最近 7 天 / 最近 30 天 / 更早”. When the chart is not the account holder, a secondary line shows the chart name under the title. A session title is named when it is created; opening a stored session must not rename it. updatedAt advances only on conversation activity, including rectification turns, choice, adopt, and stop. Opening, refresh, and metadata PATCH do not bump it. A ?c= that is not on the loaded page is looked up with GET /api/sessions/{id} before anyone may say it was deleted. Locked by frontend/tests/session-open-preserves-identity.test.ts and frontend/tests/session-lookup-unlisted.test.ts.
• Request behavior: existing sessions remain selectable for reading while a request is active; creating or sending another request stays locked until the active request settles.
• Surface: translucent warm-gray sidebar; current uses a white glass surface and deep-brown marker.

Sidebar shell

• Composition: provider, fixed header, one scroll-owning content region, fixed footer, trigger, rail, and flexible chat inset.
• Trigger placement: the single visible collapse/expand trigger sits beside the active session title in the chat header. The sidebar brand row has no duplicate trigger.
• Desktop: 288px expanded by default at 1024px and above; 64px collapsed icon rail.
• Tablet: 64px collapsed by default from 768px through 1023px; 240px when expanded.
• Mobile: no icon rail; an off-canvas drawer uses min(86vw, 320px) and closes through its scrim or Escape.
• Collapsed content: logo, new-chat action, reports action, one history expansion action, and account avatar. Individual sessions do not become indistinguishable repeated icons.
• Expanded content: new chat, my reports, chart list, favorites, then history grouped by recency. Nested lists indent under their section labels. Actions, section labels, and session rows share 18px icons, caption/body type, and ink/muted tokens. Empty untitled sessions stay off the history list. Pin is favorite; archive stays in the session menu, not as a history-header toggle. The history list loads 40 rows at a time and silently appends the next page at the bottom.
• Scroll ownership: header and footer remain fixed; SidebarContent is the sole sidebar scroll owner.
• Scrollbar: SidebarContent, ordinary session .conversation, and the rectification house board use a quiet overlay scrollbar: transparent track, no scrollbar-gutter, and a 4px warm thumb mixed from --color-ink. The thumb stays transparent until hover or keyboard focus inside the scroller, then uses color-mix(in srgb, var(--color-ink) 26%, transparent); thumb hover uses 40%. Increased contrast keeps the thumb visible; forced colors restore the system scrollbar.
• Motion: Sidebar state changes are immediate on desktop, tablet, and mobile. The 44px trigger keeps one stable 18px sidebar glyph and never enters an intermediate scale or opacity state.
• Accessibility: Command/Control+B shortcut outside editable controls, contextual trigger labels, 44px targets, focus return, collapsed-only tooltips, reduced-motion, reduced-transparency, and increased-contrast support.
• State: session-local; reload uses breakpoint defaults rather than cookie or local-storage persistence.

Message

• Variants: assistant editorial text on canvas; user text on warm card surface; streaming; error. Streaming uses a timeline of completed steps plus the current step; the thinking body expands while streaming, collapses when answer text appears, and is stored with the assistant message.
• Identity: every assistant message carries the 32px Jyotisha logo avatar; user messages stay visually lighter and avatar-free.
• Typography: assistant body --type-body-md (16px) with serif subheadings; user body 14px.
• Tables: three-column technique audit tables keep 状态 on one line. Below 768px they stack each row as title + status, then the note, instead of squeezing 已执行 into a vertical glyph column.
• Follow-up: the latest settled consultation answer may offer two or three grounded next questions under that answer. Clicking one sends it in the current session. The composer never hosts suggestion chips. If the answer does not support a grounded continuation, nothing is shown.
• Motion: a new row enters once, through the GSAP tween in chat-message-row.tsx at the 160ms Message duration; there is no CSS entrance keyframe beside it. The trailing assistant reply is one component (LatestAssistantEntry) from its first streamed token through settlement, so settling never remounts it and never replays the entrance.

Streaming states

Every assistant reply moves through the same states on both chat surfaces, and each state has exactly one visual. The step timeline (ConsultationRunTimeline) is the only activity surface; the rectification session projects its tool trace onto the same rows and differs only in that it never shows thinking text, because the server drops rectification thinking.delta at the public boundary.

State	When	Visible	Transition in
queued	request sent, no server event yet	timeline open with one live row “正在处理…” (spinner + shimmer label), summary “正在分析”	row enters with the message
loading-method	skill.started	live method row	label swap, 120ms fade
calculating	tool.started / chart activity	live calculate row; completed rows above it show the check marker	label swap, 120ms fade
thinking	thinking.section / thinking.delta	live think row; thinking text inside the row, paced per frame	label swap, 120ms fade
composing	first answer.delta	live write row; answer text below the timeline, released per frame	answer paragraphs appear as text, no per-token animation
settled	run.completed	summary becomes “已完成 N 步”, timeline collapses in place unless the reader opened or closed it themselves; actions and follow-ups appear	180ms height transition, 120ms label fade
stopped	the reader pressed stop	whatever streamed stays; a grey caption under the body says the run stopped and was not billed	none
failed	run.failed, network loss	whatever was received stays in place; the message carries no inline banner — the notice goes to the composer notice / error line	none

Text release is paced, not animated: the frame buffer commits at most once per animation frame and reveals max(2, ⌈backlog ÷ 12⌉) characters per frame, so a burst catches up in about twelve frames and a slow model never reads as stalled. The reader's own toggle on the timeline always wins over the state default. Under prefers-reduced-motion: reduce the collapse and the label fade are instant; the pacing stays, because it is content arrival rather than decoration.

Suggestion card

• Structure: topic label, question, directional icon. Categories are not numbered because they have no required order. At tablet widths, the cards stack into one column so Chinese questions keep natural phrase boundaries beside the persistent sidebar.
• Surface: warm light cards; the lead card uses the pale brown emphasis surface and border instead of a dark block.
• States: default, hover, active, focus, disabled, loading, fallback notice.
• Visibility: the initial cards, one per consultation domain, remain visible while the user types a custom question. Clicking a card starts that consultation immediately instead of filling the composer; the cards leave once the session receives its first user message.

Personal report centre

• Structure: full-page archive on the page floor. A compact back control, serif page title, supporting copy, one generate action, then a list of report cards.
• Surface: --color-canvas-soft floor; cards use --color-canvas, a warm hairline, and --radius-lg. No drop shadow. Status is a caption badge, not a colored block.
• Typography: page title uses --type-display-lg / --font-display at weight 400 with text-wrap: balance. Card titles are --type-title-md at weight 500. Body stays --type-body-md or --type-body-sm.
• Width: 900px centered, matching long-form chat reading. Cards stack below 720px.
• Actions: “生成完整报告” is the one filled action. A ready report keeps “查看报告” as the primary document action and “导出报告（.md）” beside it. The export downloads the same longform Markdown the detail page renders. Generating copy is one-step (“正在生成报告，大约 10–30 秒”); there is no chapter-count progress. Card summary is a deterministic excerpt of the Markdown 「摘要」 section, stored on the cover document at generation time.
• States: loading, empty, populated, generating, ready, failed, unauthorized, list error. Export work uses the shared inline spinner inside the initiating button, reports a short row-local error, and never starts a second writing flow. A missing Markdown appendix is an old report: the detail page asks the reader to regenerate.
• Accessibility: back, generate, refresh, and row actions are 44px. Status text uses a live region while a report is generating.

Personal report reader

• Structure: sticky screen chrome (back, secondary print, primary “导出报告（.md）”), then the longform Markdown body with a sticky heading TOC. The five-chapter writer document is storage-only and is not rendered. Reports without Markdown show “旧版本报告，请重新生成”.
• Surface: page floor --color-canvas-soft; the Markdown article is a --color-canvas sheet with a hairline and --radius-lg. Print flattens the sheet, hides chrome and the TOC, and pins the light palette.
• Typography: Markdown h2 uses --type-display-sm serif at weight 400. h3 uses --type-title-md sans at weight 500. Body is --type-body-md at 1.65. Honesty labels (blocked / conflict / parameter_sensitive) stay visible; the reading-nav and quality-matrix sections are not collapsed.
• Charts: a rehype pass groups each #### chart heading (optional note paragraph, then the jyotish-chart fence) into .personal-report-chart-card and consecutive cards into the existing .personal-report-chart-grid. A lone card uses is-single. The grid is two columns; print and the 760px breakpoint stay one column. Do not float chart headings or figures, and do not use negative margins to fake columns. Occupants are one-character Chinese names plus integer degree (日 12°), with 逆 after the name when retrograde (土逆 3°). House corners show rasi numbers 1–12. Chart JSON fences are stripped from the .md download. Markdown still uses react-markdown + remark-gfm, skipHtml, and no rehype-raw. The article tree is memoized; TOC highlight state lives in ReportToc, not in PersonalReportMarkdownView.
• Accent: headings stay ink. Dark ink is never a page-scale rule or card edge.
• Tables: wide Markdown tables sit in overflow-x: auto wrappers; print unwraps them.
• Width: 1120px for the reader chrome so the TOC rail can sit beside the article; the TOC stacks into a drawer below 860px.
• States: loading, generating, timed-out, unauthorized, not-found, failed, invalid, network-error, markdown-ready, legacy-unavailable. Waiting uses InlineSpinner and one-step copy.
• Accessibility: back, print, and Markdown export are 44px. Generating copy uses role="status". Print remains keyboard-initiated from the chrome button. Markdown is rendered with react-markdown + remark-gfm, skipHtml, and no rehype-raw.

Product entrypoint card

• Structure: the homepage daily-reading and birth-time cards are single native-button targets stretched across their article surface. Content remains semantic card copy. On two-column viewports a compact action label and arrow sit at the trailing edge; on a stacked homepage they sit under the supporting line, leading-aligned, so a short label like “深入看今日” does not float to the opposite corner from “开始新的生时校正”.
• Copy: chat history titles daily readings as “8月22日 · 今日节奏”, typed natal questions as “事业 · …”, and rectification as “8月21日 · 生时校正”. Clicking the daily card starts a consultation session immediately; it does not place the question in the composer. Private model instructions are selected by a closed entrypoint identifier and expanded only on the server. The homepage no longer shows a “从一个主题开始” grid; leftover guided_topic values in stored sessions still pin domains when replayed.
• States: default, whole-card hover, pressed, focus-visible, and disabled. The card surface—not an inner promotional button—carries the interaction feedback.
• Responsive: cards stack below 900px without introducing a large nested button. Stacked cards hug their copy instead of stretching to a min-height; the footer stacks supporting copy above a leading-aligned one-line action.
• Accessibility: each card exposes exactly one native button with a descriptive accessible name, preserves a visible focus ring, and meets the full-card touch target.

Start greeting

• Content: invite the user to ask what matters now; do not repeat that birth data is ready or explain setup state.
• Timing: use the browser's local hour: morning 05:00–10:59, noon 11:00–13:59, afternoon 14:00–17:59, evening 18:00–22:59, and late night 23:00–04:59.
• Variation: each time band has three concise prompts; select one once per visit so re-renders do not change the sentence.

Account popover

• Structure: identity header, then 个人资料 / 星盘资料 / 通用设置 / 账户与点数 (with the current balance), theme preference, divider, and logout.
• Surface: 280px elevated canvas popover anchored above the sidebar account trigger; warm hairline, existing elevated shadow, no nested cards.
• States: closed, open, hover, focus-visible, and logout confirmation.
• Accessibility: aria-expanded, aria-controls, menu semantics, 44px rows, outside-click and Escape dismissal, and focus return.
• Billing: the 账户与点数 row opens the settings dialog on the billing pane. It does not leave the homepage.

Settings dialog

• Structure: one fixed chrome for four panes — 个人资料, 星盘资料, 账户与点数, 通用设置. Left nav is 176px and does not scroll; the title bar stays put; only the right-hand content pane scrolls. Logout stays a separate 400px confirmation.
• Width / height: desktop width: min(100vw - 32px, 880px); height: min(84dvh, 640px). Switching panes does not change the frame. At ≤767px the dialog is full-screen with four equal tabs along the top.
• Personal profile: one row of avatar editing (48px preview, eight palettes, 换一个形象) plus nickname and login email. No duplicate 管理星盘资料 button.
• Chart library: list first (self row, other rows, 添加其他人). A row opens a detail with ← 星盘资料. Other details own 设为默认 / 删除 / 用于合盘 and that person's synastry history. The add form is a view, not an always-on stack.
• States: open, pane switch, list / self / other / add, saving, success, and error.

Billing pane

• Structure: summary line (balance · membership / expiry), then tabs 会员套餐 / 点数包 / 兑换码 / 订单记录.
• Actions: recommended-plan purchase is Button default. Other plan and credit buys use Button outline. Cashier still opens with window.open in a new tab. Paying copy is 跳转收银台…; pending copy is 等待支付结果. Redeem is an inline form on its tab, not a nested dialog.
• Deep links: /?settings=billing&source=…[&plan=…][&tab=…] open this pane on / and are then stripped. /membership and /membership/orders redirect here.
• Waiting: the summary renders from the in-memory account. Package cards stay empty until /api/payment/packages arrives. No spinner, skeleton, or 「正在加载」.

Logout dialog

• Structure: confirmation title and explanation, cancel action, and destructive confirm action.
• Width: 400px desktop maximum.
• States: open, signing out, and error.

Admin panel and data table

The admin is not built from this design system. It runs on antd + Refine, and src/app/admin/admin.css only re-skins antd to sit near the product palette (warm floor, hairline borders, the same body font). Admin routes deliberately do not load globals.css — that isolation keeps the 33 KB chat stylesheet off every admin page — so nothing here inherits the tokens above.

• Structure: antd Layout with sider, header and content, wrapped in .admin-app-shell; tables, cards, tags and statistics are antd components.
• Own classes: only .admin-app-shell, .admin-loading and .admin-text-list. Anything else must be an .ant-* override inside admin.css.
• Colors: admin.css writes literal hex because it cannot see the tokens. Those literals must stay in sync with the palette above by hand; this is the one sanctioned exception to the no-raw-color rule.
• Content width: 1200px centred, set by antd layout, not by .admin-scroll.
• Loading: antd <Spin>, outside the waiting vocabulary in section 9.

6. Motion & Interaction

--ease-out is cubic-bezier(.22, 1, .36, 1) and is the only easing curve in the system.

Type	Duration	Easing	Usage
Micro	120ms	ease-out / --ease-out	Button, row, popover and tooltip feedback
Standard	180ms	--ease-out	Dialogs, onboarding cards, auth steps
Message	160ms	--ease-out	A message row entering the transcript
Thinking collapse	180ms	--ease-out	The step timeline opening or closing in place (grid-template-rows 0fr ↔ 1fr)
Timeline label swap	120ms	ease-out	“正在分析” → “已完成 N 步”, and a live row's label changing
Text reveal	per-frame release, not a duration	none	Streamed answer and thinking text; see Streaming states
Sheet	280ms	--ease-out	Rectification sheet rising from the bottom
Spatial	Instant	None	Sidebar state changes and mobile drawer

Looping animation is covered separately in section 9.

Only transform, opacity, and color/filter transitions animate. Reduced-motion disables non-essential animation. Motion communicates state; decorative looping is limited to an active loading state.

7. Depth & Surface

Strategy: warm tonal shifts, restrained translucency, and fine hairlines. Most depth comes from the page floor, main canvas, warm cards, and selected white glass. Standard UI uses no drop shadow. Modal, popover, floating-control and raised-sheet depth use one restrained two-stage token: --shadow-elevated: 0 1px 2px rgba(29, 29, 31, .07), 0 12px 28px -16px rgba(29, 29, 31, .18). A second, quieter token, --shadow-soft: 0 1px 2px rgba(29, 29, 31, .06), 0 8px 20px -18px rgba(29, 29, 31, .2), belongs to surfaces inside the reading column — the conversational narrative card, the composer field within a session, the starter theme card's focus state and the auth mode tab. Floating controls and overlays (jump to latest, popovers, sheets) always take --shadow-elevated. Interactive rings use 0 0 0 1px or the focus ring; no generic card shadows, no utility-class shadows, no atmospheric gradients. When transparency is reduced, frosted surfaces fall back to opaque warm neutrals.

8. Agent wording and accuracy boundary

The Birth-Time Guide Agent controls wording only: it may choose a safe tone or extract a reviewable draft, but it cannot select evidence domains, change nextAction, rank candidates, set confidence, or grant save/apply permissions. Those decisions remain in the deterministic, versioned journey state machine and its server-side scorer.

confidence is an internal, versioned safety gate for this product flow. It is not an external oracle, clinical claim, or proof from calibrated real cases. Until matching external-engine parity and real- case validation are complete, low and medium results never apply a minute, and high results still require explicit confirmation of the matching representative time. Journey telemetry is limited to metric name, phase, and optional confidence; it never records messages, dates, coordinates, case IDs, or user IDs.

9. 等待与加载

等待按语义只分三类。同类必须共用同一套实现；不要为新入口再写一套旋转或呼吸。

类别	语义	组件 / 样式	时长	prefers-reduced-motion: reduce
整页 / 整块阻塞	首页揭幕前的两阶段载入（载入账户 → 准备对话）、生时评估浮层	AppLoadingIndicator（轨道环 app-loading-orbit）	1.4s linear	全局 * 规则把循环收成一帧；不要改它的 DOM
行内 / 局部等待	出生地解析、两个会话面时间线的 live 步、兜底活动面板的 live 行、个人报告列表与详情	InlineSpinner（inline-spin）	0.8s linear	animation: none，收成静止圆点，不要半圈圆弧
流式生成中	引导语打字、时间线 summary 与 live 行的文案	onboarding-caret / agent-activity-shimmer	700ms steps / 1.6s linear	保持现有全局降级

Agent 的 live 标记只有 InlineSpinner 一种。曾经并存的 canvas 小球（thinking-orbs）已移除，不得再引入第二种 live 标记。

校正面的所有等待复用行内等待：进入前的 hydration 在揭幕之前完成，进入后唯一的等待形态是时间线 live 行（含「正在准备下一个问题…」这一条独立 live 行）。区间交付卡只挂在最新那条采用旁白下面，不得留在更早的采集/区分题下。有未答的采集或选择题时卡仍在，「更像这个」置灰并写「先答完上面这道，再选时间」，不得整卡消失。卡上至多三列并排，相同性格句只写一次，点「更像这个」即采用该列分钟，按钮显示「正在采用…」或「已采用」。采用过程中整张卡留在原处，不得因 busy 卸掉。采用后前事核对结束走 verified_idle：一行收尾文案跟在卡片下面、与助手列对齐，没有 live 行、没有重载、没有采用状态条。卡片与右栏细则见 §11、§12。

首页只揭幕一次。揭幕前的加载屏分两阶段：先取账户、模型目录与会话列表，再并行取今日星语与校正入口摘要，并预热校正分包；全部就绪或 4 秒预算到期（BOOTSTRAP_PREPARE_TIMEOUT_MS）才揭幕。揭幕后不得再出现任何阻塞等待或组件级 spinner：今日星语未到显示静态文案「今天的星语还没写出来。」（不带 aria-busy），校正卡用无摘要文案，内容到达后静默替换。登录后的空首页只剩问候语、今日星语卡、生时校正卡和输入框，没有主题卡。切换到消息尚未缓存的会话时消息区留白并只给 sr-only 文案，不转圈；揭幕后按侧栏顺序后台预取最近 5 条会话（SESSION_PREFETCH_COUNT）让常见切换零等待。轨道环消失后不得再换一套动效继续等。

报告生成等待态

个人报告要写几分钟，属于"等到有实质进度可报"的一类，因此在上表三类之外单独规定：只有准备阶段用 InlineSpinner，进入写作阶段后换成分章进度，不再转圈。

三个阶段跟随 worker 自己的 phase 阶梯（queued / loading_context / generating_report → section:<id> → persisting_report）：

阶段	屏幕上	文案
准备	InlineSpinner	正在准备你的星盘证据
写作	分章进度条 + 章节清单，无 spinner	已完成 N / M 章
收尾	InlineSpinner	正在整理成文

硬规定：

• 进度条按章分格，一格一章，不画百分比。 job 的 percent 在 0→30 和 90→100 是瞬间跳变，只有中段跟随真实工作量；画成线性条等于演出后端没做的动作。格数恒等于章数，条与清单不可能互相矛盾。
• 不做时间插值，不显示预计剩余时间。 界面上没有任何按定时器推进的东西；后端没动，屏幕就不动。章节耗时被重试放大到两倍以上，报不准比不报更伤。
• 正在写的那一章由行状态判定，不由 phase 名判定。 section:<id> 命名的是刚写完的那一章；且章节列表按 section_id 字典序返回，不是写作顺序，所以"已完成数 + 1"也会指错。唯一正确的判据是 pending 且已被认领。
• 停滞满 90 秒（REPORT_PROGRESS_STALL_MS）当前章文案改为「用时较长，仍在写」。不写第几次尝试——attemptCount 不出服务端。
• 写作失败的章仍然计入完成数，进度条照常前进；走到头不等于全部成功，收尾按 summarizePersonalReportFailure() 的白名单文案说明。
• 可显示的只有章节名与章节状态（用户交付物的结构）。attemptCount、原始错误码、lease、job id、payload 一律不出服务端——与 BUG-043 的边界一致：那条禁止的是把后台评分状态渲染成用户要管理的面板，本处是只读等待屏上的交付物结构。

Admin 的 antd <Spin> 是独立设计系统，不在此表。

10. 生时校正常驻时间轴

校正是最长的流程，唯一能表达「正在收敛」的量是范围宽度。它此前只以范围变化句的形式散在消息流里，滚上去就看不见。时间轴把这个量变成常驻形态。

它是一条只读的横条，钉在校正对话上方，回答「我在哪、还有多宽」；「选哪一分钟」仍然只由交付卡回答。

三条硬规定

一、它是 .rectification-workspace__chat 的第一个 grid 行，不是 position: sticky。 该容器现在是三行：var(--rectification-timeline-height) minmax(0, 1fr) auto。条位于滚动容器 .conversation 之外，因此 scrollHeight 不变，use-conversation-scroll-anchor 的贴底距离仍然精确，它的 ResizeObserver（只观察滚动容器的直接子元素）也永远看不到这条。该 hook 不因本组件改动一行，校正面不得出现第二套滚动跟随。若改成滚动容器内的 sticky 子元素，还会撞上 BUG-218/252 的老问题：容器留了 padding-bottom 时，sticky 子元素被内容盒夹住，永远贴不到可视底边。

二、条高固定，从首次渲染起就占位。 这是正确性要求，不是视觉偏好：条在滚动容器外，高度一变就改 clientHeight，而没有任何观察者会因此重新跟随——贴底的读者会看着内容悄悄滑出视野底部且无法恢复。同理，Case 未就绪时渲染等高的空骨架（data-state="pending"），不得用 spinner、不得用「正在加载」文案、不得让条晚一步挂载。桌面 64px，767px 以下 56px；56px 等于既有的 --rectification-jump-clearance（44px 触控尺寸 + space-3），不新造常数。

读数和轴的水平内边距对齐助手列：桌面 space-8 + --assistant-content-inset，767px 以下 space-4 + --assistant-content-inset，与 .message-list 沟槽和头像让位相同。底边发丝线和背景仍拉满聊天列，不把条做成第二条滚动容器。

三、条上只有两个元素：轴本体（区间带 + 候选标记 + 刻度）与区间读数（05:07–05:09 · 3 分钟）。以下一律不得加回来——每一条都是被明确砍掉的：

不得出现	理由
范围变化句	服务端已写进落库助手消息，BUG-588 防复发要求它在那里；条上再写=同句同屏两次
「仍在范围内 N / 已排除 N」计数与图例	实心=在内、空心=已排除，答完第一题即自明；图例是过度提示的典型形态
阶段标签（时段 / 分钟）	block_scan / minute 是后台词汇，贴近 BUG-043 红线
「已对照 N 件经历」	归交付卡；卡上是人话「N 件里 M 件对得上」，不是计数条
「时间轴只读」注脚	在解释一个不存在的东西；没有元素看起来可点，就不需要声明不可点
预计剩余时间、定时器插值动画	与报告进度条同一条原则：不得演出后端没做的动作

轴与标记

• 轴 = 当前搜索窗口（candidate_range），不是开场窗口。 开场窗口不是定值（±15 / ±30 / ±60 / ±120 / 整天），且放宽会顶穿它（BUG-572：±15 → ±30 → ±60 → ±120）。窗口变化时轴重新对到新窗口，区间带与标记用 CSS transition 过渡到新位置（prefers-reduced-motion 由全局 * 规则收成一帧）。窗口不变时轴稳定，收窄照样读得出来。
• 候选标记一律等大，只分在范围内 / 已排除。 不得按 relativeSupport / probability_percent 分级（尺寸、深浅、粗细都不行）：BUG-560 状态是 blocked，候选间相对支持度 7–9 分（满分 100），校准显示分钟级几乎无区分力，分级显示等于用视觉编码放大统计上不显著的差异。被排除的点留在原地变空心、不消失——用户由此看见自己刚才那一答排掉了哪几分钟。
• 时段阶段（block_scan）不画分钟点，区间带覆盖整个窗口。那一刻确实什么都还没排除，写「24 小时」是事实而非占位。
• 跨午夜的窗口（late_night 是 23:00–03:59，末端早于始端）按次日展开，轴保持单调。
• 条上不得出现 rectification-step-state 类名（BUG-575 防复发）。

11. 区间交付卡

交付对象是区间里并排的候选分钟，不是支持度数字，也不是逐行空差异。

相同的句子只写一次。 两列或三列共有的 D9 / D10 / 月宿性格句提到卡片顶部（「三个时间的事业盘都在巨蟹座：做事以照顾人为主」）。列内只留有差别的句子；某列没有差别句就不显示性格块，不写「同上」。单列不提升共享句。

每列 = 时间 + 相对可能性 + 至多三行 + 「更像这个」。列内不再有 <h3>。经历对照由服务端拼成一行：「8 件经历里 7 件对得上，最不合的是 2024 年 5 月那段感情」。未来窗一行：「下一个值得留意的时段：2027 年 3 月前后（事业）」；算过但没有窗写「未来一年没有明显的时段」；by_time 缺键写灰字「这一分钟还没对照」，不得回退成 0 · 0 · 0 或把「没算」说成「没有窗」。用户可见文案不得出现「强相关 / 有关联 / 弱关联」。

卡顶保留范围与经历数；卡底边界句保留；「查看验证报告」默认收起。不预标「排盘用」。卡上没有「再答两道参考题」入口。风格参考题只在出卡前收集，出卡即结算。tie_break_available 仍由服务端决定要不要先问，不再驱动任何按钮。点「更像这个」走现有 accept RPC。采用过程中整张卡留在原处；已采用列按钮禁用。有活题时「更像这个」置灰。收尾句跟卡片同一列。

引擎 event_dasha_ledger_by_time / prospective_windows_by_time 的键是引擎 candidate_times 去重全集（上限 64），不是引擎分数前三。卡片仍只投影后验前三。若上一轮 64 分钟对照超过 3 秒，下一轮可以把推断层仍有效的分钟作为 column_times 传入。

12. 校正右栏盘面

右栏回答「当前按哪一分钟在看盘」，不回答「选哪一分钟」。顶部不加任何新说明文字。

本命宫位改北印星盘。 用 VedicChartSvg 渲染代表分钟的 house_table。宫位表退到星盘下方的 <details>（读屏与复制仍可用）。换分钟时只高亮变化的宫（changedHouses / lagnaChanged），不做动画。星盘组件在校正面 dynamic() 分包里，不进首页首屏。

换升时刻默认折叠。 时间轴已常驻显示范围与候选点，右栏「换升时刻」整段默认收进 <details>，summary 为「换升时刻 · N 个」；逐分钟 LayerChips 不变。「显示层」子折叠并入同一折叠。确认门折叠、两段本命上升折叠保留原样。

13. 回答的两层可见性

本命类聊天回答默认只展开口语层。从第一个 ATX H2（合同上是 ## 统一参数与原始结构，切点按任意 H2，以便模型漂移时仍能折）起的全部章节装进 <details className="answer-detail">，默认收起。骨架仍完整生成、入库、可复制、可导出；折叠只改默认可见性。

• 口语层： 第一个 H2 之前的全部内容，直接画在 .message-markdown。无 H2 的闲聊和 onboarding 打字机消息整篇留在这一层，不出现折叠块。
• 折叠层： <summary> 主标「完整分析」；副标用 <small> 写章节名，取 headings 前三个（统一参数与原始结构 写成「统一参数」，技法审计表 写成「技法审计」），多于三个补「等 N 节」。不要只写「展开」。
• 技法审计： 正文里已经有审计表时不另折一份；只有事件行、正文没有表时，TechniqueAuditDisclosure 跟在折叠块内部。没有 H2 时仍留在回答底部原位。
• 流式： 折叠块保持收起，不渲染 children，副标写「正在写…」。不得出现 spinner / 骨架 / 「正在加载」。流式结束后再解析报告 markdown。口语层在流式期间仍走 StreamingMarkdown。
• 个人报告页走 personal-report-document-view.tsx，不经过本组件。
• 窄屏表格： 三列表（技法审计）继续卡片化。四列及以上（Yoga、统一参数）在 .conversation 里横向滚动，右缘用 canvas 渐隐提示还可滑；.conversation 自身 overflow-x: hidden，页面不得出现横向滚动条。个人报告表格不走这套规则。
• 表单输入 16px： 全局 input / select 用 --type-body-md（16px）。iOS Safari 对小于 16px 的字段聚焦时会整页放大且不缩回。.otp-input 仍是 20px，.composer textarea 仍是 16px。

14. 断点

宽度切点只允许出现在 globals.css 顶部注释的白名单里。壳层切点以 sidebarViewportForWidth 为准：小于 768 移动，小于 1024 平板，否则桌面。组件级栅格（会员方案卡、校正候选、录入卡）用 640/641。报告目录在 860 塌成抽屉，因为那是第三栏的内容宽度，不是设备宽度。

禁止再引入 900 / 720 / 760 / 639 / 620 / 430 这类与壳层或彼此错位的切点。新切点必须先改白名单和 viewport-breakpoint-contract.test.ts。

15. 只读星盘页

独立 route /chart，不进 page.tsx。外壳先画、主盘先到、其余 tab 按需。不扣点、不调模型。盘面从现有路径复用 VedicChartSvg，不搬家。

/chart 是静态壳：首字节不取决于引擎。进页只请求 /api/chart。分盘（/api/varga_full）、大运 Chara（/api/dasha/chara）、西洋（/api/western）、七政（/api/qizheng）在用户点到对应 tab / 非 D1 chip 时才请求。未点的 tab 不发请求。

结构

页眉：成功时眉标「主盘直接算 · 分盘按需 · 不消耗点数」+ 标题「星盘」+ 出生资料一行。等待外壳和失败页只有标题和原因/等待句，没有眉标。不得写「打开即有」或任何速度承诺。五个 Tab 按体系分：星盘 / 基础信息 / 大运 / 西洋盘 / 七政四余。分盘 chip（D1–D30）只出现在印度「星盘」Tab 内部，不得把西洋盘或七政四余做成第 13 个 chip。

侧栏在「新建对话」之后、「我的报告」之前加「星盘」「星历」两个入口；折叠轨（64px）仍用既有 report-nav-button 图标行，当前项用白玻璃面 + 2px 深棕标记，不新造选中态。星历入口指向 /ephemeris（由另一单交付，合入前 404 是预期）。

中宫排盘参数卡

北印盘几何中心叠一张参数卡。桌面（≥768）六行：钟表时间与校正状态、出生地与经纬、岁差、交点模式、上升与月亮星宿、当前大运分运与引擎名。手机（≤767）中宫只留岁差与交点两行；完整六行改到盘下方一张卡。切点跟壳层，不另造 390。

盘内 SVG 文字用 CSS 提到 16px viewBox 单位，使约 318px 盘宽下实际像素不低于 12px。Tab、分盘 chip、返回均 44px。

三套坐标系

每一套必须在自己的 Tab 里写明自己是什么，并显式点名不能互相换算、也不能叠成「双重印证」：

• 印度盘：恒星黄道，岁差用资料里选的那一套。
• 西洋盘：回归黄道，宫位 Placidus；右栏第一张是边界卡。端点未上线时 Tab 仍在，渲染静态说明，整页不失败。
• 七政四余：宿度自角宿初度起算。必须同时出现计都派别与庙旺未闭合。端点未上线时同样只渲染静态说明。

「传统象征」是词条式释义，带边界句「不是对你个人的判断」，不得写成运势。大运 Tab 底部固定：「只有两条同时指向同一段时间才算证据，单轨命中要降一级来看。」Chara 的正式名称是 Chara Dasha（kn_rao 变体），不要写成 Narayana。

等待态

星盘页是独立文档。外壳揭幕（标题、返回）可以在主盘到达之前发生；揭幕之后填数据不得再出现 spinner / 骨架 / 「正在加载」，沿用 §9 星历页那一类静态句，不新造第五套加载动画。

时刻	文案
外壳已出、主盘未到	这一张盘还没拿到。
已点大运 / 西洋 / 七政，该路还没返回	这一栏还没拿到。
已点非 D1 分盘，分盘包还没返回	这一分盘还没拿到。
引擎 429	算盘的服务正忙，稍等几秒再打开就好。
其它主盘失败	这张盘算不出来，我们已经记录下来了。

16. 星历页

独立 route /ephemeris。侧栏入口由星盘页那一单加；本页不改 app-sidebar.tsx，合入前用直接访问 URL 验收。不扣点、不调模型。html, body 仍然 overflow: hidden，本页用 .ephemeris-shell 自管滚动，和报告中心同一做法。

• 结构： 顶栏返回对话；标题「星历」；日期条；今日五要素；当日行运；未来九十天；底部出口卡。顺序固定。
• 日期条： 「前一天 / 今天 / 后一天」三个 ≥44px 真按钮。切日期立刻换五要素和行运；没有 spinner、骨架或「正在加载」。数据未到时写静态句「这一天的五要素还没拿到。」「这一天的行运还没拿到。」
• 五要素： 桌面五张卡一行（星期、月相日、月宿含第几足、瑜伽、迦那）。767px 以下收成一张卡里的五行，标签左、值右。Yoga / Karana 的吉凶只照搬引擎标签（吉 / 中 / 凶），不写成建议。卡片下固定一行：「这一段按 Lahiri 岁差算，和星盘页用的岁差不是同一套。」行运段不加这句。
• 当日行运： 九曜的星座、度数、相对本命宫位、顺逆。桌面表格，767px 以下每行改成带标签的堆叠。没有本命上升时，相对本命列为空，并写「还没有本命上升，相对本命这一列空着。」
• 未来九十天： 按日期升序只写事实（「某星 进入 某座」「某星 停滞转顺 · 度数」）。/api/ephemeris_events 未上线时整段静态说明：「换座和停滞还没接上。这一页其余部分不受影响。」不得让整页失败。
• 出口： 底部一张卡，一句「这一页是天象本身，不是对你的判断。」主按钮「带这天去提问」把当前日期预填进对话草稿并回到 /。
• 等待： 揭幕后不得再出现 spinner / 骨架 / 「正在加载」。未登录是静态「请先登录」加去登录，不是转圈。
• 文案： 这一页是天象本身。不得写运势结论，不得把三套坐标系换算或叠加。
