 ### Personal report centre
 
-- **Structure:** inside the app shell, not a page of its own. The name 「我的报告」 sits in the 46px header with 「生成完整报告」 as the header's one action; the body starts straight at 「报告记录」 and the **row list** of reports. The supporting paragraph (「有填报到分钟的出生时间即可生成……」) and the 「共 N 份 · 已完成 N 份」 overview line above it were removed on 2026-09-28 (TASK-self-edit-avatar-menu-20260928 S3, product: 「这里的提示去掉」); the minute requirement still lives in the 生成 button's hover title.
+- **Structure:** inside the app shell, not a page of its own. The name 「我的报告」 sits alone in the 46px header. The body opens with the **generate card** (`.report-center-create`, 2026-09-29, product sketch): a centred `--color-canvas` sheet with a file icon, 「生成个人报告」, one line 「创建后即可离开，完成时下方列表会自动更新。」 and the filled 「生成报告」 button — the page's only generate entry; the header button was deleted rather than kept as a second one. Below it, 「过往的报告」 heads the **row list** of reports; with none yet, a single quiet line 「还没有个人报告。」 replaces the old second big empty card.

   It used to be a standalone full-screen route with a `report-center-shell` root, a `report-center-topbar` holding one 「返回对话」 link, and a `report-center-hero` with a page-sized h1 — the sidebar vanished the moment you opened it, and the only way back was that link.
 - **Row list, not a card grid:** `.report-center-list` is one column of `.report-center-row`, hairline-separated by a 1px grid gap over a `--color-border` ground so each boundary is a single rule rather than two touching borders. A card grid costs one scan per card; past five or six reports the reader is looking for state, and a single column puts every status chip on the same x. D12.
 - **Row anatomy:** status chip, then the title at `--type-title-md`/500, then the meta line (creation time · depth · themes) at `--type-caption` with `tabular-nums`, then — for a ready report — its stored card summary, or for a failed one the failure reason. Actions sit right-aligned on the same row and wrap under the body at the global 767px cut.

 - **Surface:** `--color-canvas-soft` floor; completed rows are paper, other rows canvas, with a warm hairline and `--radius-lg` on the list as a whole. No drop shadow.
 - **Metadata and deletion:** full Chinese date · localized depth · localized themes; unknown IDs remain readable verbatim. Every row has a 44px top-right `⋯` menu containing only 「删除」. It opens the row-local 「确定删除这份报告？」 with 删除 / 取消, never `window.confirm`. Failure stays in that row; success removes it and invalidates list cache. In-flight GET responses cannot resurrect a deleted row.
 - **Width:** 900px centered, matching long-form chat reading. Rows stack at the global 767px cut.
-- **Actions:** “生成完整报告” is the one filled action. A ready row keeps only “查看报告”; export is selected inside the reader so the list does not duplicate that action. Generating copy is one-step (“正在生成报告，大约 10–30 秒”); there is no chapter-count progress. A failed row states the reason in place and offers no second generate entry — the header already has one. 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. First-screen loading uses `SecondaryPageShell` waiting copy 「报告列表还没拿到。」 — never a spinner, skeleton, or 「正在加载」. Export is local to the ready reader's drawer and never starts a second writing flow or fetch. Download failures remain in the open drawer; only success closes it and emits a toast. A missing Markdown appendix is an old report: the detail page asks the reader to regenerate.
 - **Accessibility:** generate, refresh, and row actions are 44px. The generating row's chip is a live region; a failed export is an alert.

 - **Buttons on the report surfaces:** the BUG-1078 report-only override (2026-09-28) was replaced the same day by the site-wide solid-button pair (BUG-1079, see Button); report buttons look as before. Outline buttons there (the header 「生成报告」 while submitting) now fade like outline buttons elsewhere instead of the report-only grey. The selected export preset is `--color-canvas-muted` + `--color-ink` + a `--color-ink-secondary` edge, not the `--color-action-soft` fill (a red-brown block in dark mode).
 - **分块导出对话框 (2026-09-24):** native modal `<dialog>`, bottom-aligned below 860px and centered at ≥860px, app colours only. Desktop is viewport-centered (`inset: 0; margin: auto`) regardless of sidebar state, width `min(720px, 92vw)`, max-height 80vh, with full `--radius-lg` corners. Its flex panel is capped at `calc(80vh - 2px)` to reserve the dialog border; desktop rules follow the narrow-screen dvh upgrade so 70dvh cannot override them. Below 860px the content-column offset, bottom alignment and at most 70vh/70dvh remain unchanged. Header and single export footer stay visible; the block list scrolls, two columns at the existing 860px breakpoint. Escape, backdrop or 关闭 dismisses; focus returns without scrolling. All controls have 44px targets. No spinner, clipboard or extra fetch.
-- **Export selection:** default 常用 selects every body block from the single outline's lossless source slices (lead = 摘要); 全部分盘 and 仅核对表 replace the selection. Manual toggles clear preset highlighting. 全选 / 取消全选 works across all groups; zero selected disables export. Counts are actual Unicode code points in serialized block text, including SVG markup, not approximate prose counts.

Manual toggles clear preset highlighting. 全选 / 取消全选 works across all groups; zero selected disables export. Counts are actual Unicode code points in serialized block text, including SVG markup, not approximate prose counts. Beside them the header shows the file size for the whole report and for the selection — the UTF-8 byte length of exactly what would download (`TextEncoder` over `joinExportBlocks`), as 「约 186 KB」 / 「约 1.4 MB」, never a per-character estimate.
 - **Export content:** full body alone remains byte-identical to the retired ordinary Markdown export. Selected chart/table blocks append new content; selecting all groups is not byte-identical to body-only. D13 requires safe SVG in each chart, reusing the projected engine SVG or the existing hook-free Vedic drawing; offline fallback uses readable monochrome glyphs/legend and presentation attributes. No chart JSON fences or internal audit fields. Fact-table labels/precision/subtables match the reader. Full body uses the historical filename; excerpt adds `-节选`. The existing downloader appends `.md`.
 
-- **Structure:** inside the app shell, like every other secondary page — `/reports/[reportId]` was the last standalone full-screen route, and opening a report used to drop the reader out of the app entirely. 「个人报告」 sits in the 46px header; below it the reader owns its own scroll boundary, carrying the sticky screen chrome (back and the export icon button) and then the longform Markdown body beside a persistent TOC rail. Every phase — loading, generating, timed-out, and each error — renders inside the same shell, so the way back is always the rail. 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”.

+- **TOC levels (2026-09-29):** chapters (`##`) are `--color-ink` at weight 600 with `--space-3` above each new chapter; sections (`###`) are indented `--space-5` and stay `--color-ink-secondary`. The two levels read apart without relying on the current-item pill.
+- **到底部 / 回到顶部:** one floating pill (`.report-edge-jump`, fixed bottom-right, same look as the chat's 跳到最新). It reads 「到底部」 until the reader is within 480px of the end, then 「回到顶部」 — never both. Sections below the fold mount lazily, so the click first mounts every section synchronously (`flushSync`) and then scrolls to `scrollHeight`, landing on the real end in one click. It is not a scroll follower and owns no anchor; it is hidden on paper.
 - **TOC rail:** a persistent right-hand column built from the outline's own `##`/`###` ids — no second slugger, and nothing that touches the chart-grid rehype pass. It is sticky under the report's own action bar, highlights the section in view via `IntersectionObserver`, and marks it with `aria-current="location"` plus a 2px `--color-action` bar. Placement is explicit (`grid-column: 2`) rather than DOM-ordered, so the narrow-screen drawer can stay first in the source. Below 860px the rail is gone and what remains is the collapsed 「目录」 drawer.
 - **Paper stays paper:** the rail reads in the app palette because it is chrome. `--report-paper` / `--report-rule` / `--report-accent` are the document's own, deliberately out of step with the app accent, and nothing in this surface puts them on chrome or takes chrome colour onto the page. D11, continuing D3.
 - **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. Report tables (Markdown and fact tables, never chat bubbles) carry a header band of `--color-ink` at 6% and zebra rows at 3%, both mixed into transparency so they work on paper and on the dark sheet; print lightens them to 5% / 2.5%.
 - **Width:** 1120px for the reader chrome; the article takes `minmax(0, 1fr)` and the TOC rail `minmax(11rem, 15rem)` to its right. The TOC collapses 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.
