报告前面加一段模型写的解读（issue #113 R1）

引擎在同一份 packet 上给出与对话同源卡相同的事实（include_reading_facts），
报告任务交付前用一次结构化模型调用写八节解读，校验不过或失败就不出解读、
报告照常交付。解读存在计算快照里，读接口一起返回，页面放在引擎正文之前，
后面标「计算依据」。用量按实际 token 记账（BUG-1460、BUG-1461）。

 - **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.
 - **报告标题 (2026-10-13, BUG-1316):** the Markdown `h1` is the report title. It uses `--font-display` at `--type-display-md` (larger than the `h2` `--type-display-sm`), weight 500, with `--space-2` above and `--space-3` below. Under it, one caption (`.personal-report-md-byline`, `--color-ink-tertiary`, `--type-caption`, body face) reads `{名字} · 生成于 YYYY-MM-DD`, or `Generated` in English. No name: date only. The title already contains the name: date only, the name is not repeated. The name comes from the signed-in read (`subjectDisplayName`); it is not added to the public projection or the export. Old reports without a name still show the date.
 - **开篇重点卡 (2026-10-13, BUG-1316):** the first chapter is one card (`.personal-report-focus-card`) drawn from a `jyotish-focus` fence. The engine writes the JSON; the page only parses it. First row, 「现在走的大运」: 主运 / 子运 / 次子运, each the planet's Chinese name plus `YYYY.MM – YYYY.MM`, in a wrapping row. Then 事业 / 财富 / 婚恋: 「第 N 宫主 · 行星 · 落第 M 宫」 and two tags (`.personal-report-focus-tag`, same muted pill as `.chart-role-badge`: `--color-canvas-muted`, `--color-ink-secondary`, `--type-overline`). The last line is the caveat at `--type-caption` / `--color-ink-tertiary`. No MD / AD / PD on the card. A bad fence says 「重点数据无效」 (English "Focus data is invalid"), the same invalid line as a bad chart, and does not echo the JSON. The card wraps; it does not scroll sideways. Tokens only, so light and dark both stay readable. Reports with no fence render as before. Export turns the fence into those same words; the file has no raw JSON. The public projection keeps a public fence the way it keeps `jyotish-chart`, and does not add a name field.
+- **开篇解读 (2026-10-27, issue #113 R1):** a Chinese report with a stored reading shows it right after the title / focus card and before the first engine chapter: one `h2` 「解读」 (`#report-reading`, also the first entry in the contents rail and drawer), then eight `h3` parts 总评 / 性格 / 事业 / 财富 / 感情 / 健康 / 现在这几年 / 几条建议, each one to four plain paragraphs in the article's own body type. No card, no icon, no badge: it reads like the rest of the article. After it, a quiet label 「计算依据」 (`.personal-report-basis-label`: `--type-overline`, `--color-ink-tertiary`, a 1px top rule) introduces the engine report, which is unchanged. In paged mode the reading sits on chapter 1 only. The reading arrives in the same read as the report: no loader, no second request, nothing appears after reveal. English view and reports without a reading render exactly as before.
 - **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. The chart section opens with one caveat line under its heading ("分盘对出生时间敏感，原始计算供核对，不单独增加结论的确定性。", engine-written, English in the English edition). Each chart is drawn once: the trailing 「分盘核对」 block only draws structured charts the body has no fence for — the export's rule, shared via `fencedReportChartIds` — so a current report has no trailing block at all and an older report keeps only the charts its body lacks (BUG-1203). 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%.
