报告和合盘的中英切换能看出选中了哪个（BUG-1445）。

选中项改认页签自己的标记。边框和文字用主题色，背景保持中性。整篇和自选重新描上主题色边框。

检查：language-switch-selected 1 通过；report-buttons-scope 与 class-name-definition-contract 共 9 通过。两轮都是 0 失败，退出码 0。

+## BUG-1445 | 报告和合盘的中英切换看不出选中了哪个
+
+- 状态：resolved
+- 首次发现：2026-10-26
+- 最近更新：2026-10-26
+- 影响面：个人报告的语言切换、导出抽屉里的语言分段和「整篇 / 自选」、合盘报告的语言按钮。勾选章节的方框没改。
+- 用户现象：中文和 English 看起来一样，看不出当前是哪一种。导出时「整篇报告」和「自选章节」也没有主题色边框。
+- 触发条件：这三处换成页签之后，页签用 `data-active` 和 `aria-selected` 表示选中。旧样式仍只认 `aria-pressed` 或 `aria-checked`，而且未分层的透明底盖住了组件库的选中色。
+- 根因：选中规则对不上页签实际写下的标记。导出范围的两张卡片也不再带原来的卡片类名。
+- 修复：三处选中规则改为认 `data-active` 或 `aria-selected="true"`。边框和文字用主题色，背景保持中性。整篇和自选重新带上卡片类名，选中时描出主题色边框。
+- 验证：`frontend/tests/language-switch-selected.test.tsx` 渲染这三处和导出范围，选中项与未选中项的标记不同，且只有选中项命中主题色规则。`report-buttons-scope-20260928.test.ts` 与 `class-name-definition-contract.test.ts` 通过。
+- 防复发：上面的渲染测试，以及源码里不再保留这三组只认旧标记的选中规则。
+- 相关记录：issue #111 验收 U2。#108、#109。BUG-1078。
+- 复发自：无

 - **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).

Below 767px it slides up from the bottom (`data-side="bottom"`, up to 85dvh). App colours only. Top to bottom: title 「导出报告」 with a × (读屏名「关闭导出」); segmented tabs for language (`aria-label="导出语言"`, 中文 / English) only when an English edition exists. They start on the edition being read and do not switch the page. There is no AI caption. Without an English edition, opening the sheet raises one info toast (id `report-export-english`) saying why. Then two segmented tabs (`aria-label="导出范围"`) 「整篇报告」 (subline counts 章正文 / 张分盘 / 张核对表) and 「自选章节」 (the second tab also carries 「只带走需要的部分」); only in 自选, a plain checklist grouped 正文 / 分盘 / 核对表, each group one tri-state checkbox (✓ / − / empty) plus a chevron, 正文 open and the other groups folded. Rows are borderless 44px lines, no per-block character counts. The footer button does not show a file size: 「导出整篇」 / 「导出 N 项」 / disabled 「先勾选要导出的部分」. Selected states (issue #90, 2026-10-21, overrides the 2026-09-30 neutral rule): the scope card's border and radio dot, checked / mixed boxes, and the selected language segment use `--color-action-strong` (text `--color-action`); backgrounds stay neutral; never `--color-action-soft` or `--color-action-fill` (BUG-1078: no dark red-brown block in dark mode).

The language segment and the 整篇 / 自选 cards (`report-export-mode`) match `[data-active]` or `[aria-selected="true"]`, the same mark the chart-page tabs use. They do not look for `aria-checked` or `aria-pressed` alone. Escape, backdrop or × dismisses; focus returns without scrolling. No spinner, clipboard or extra fetch.
 - **Export selection:** 整篇 = every block of the chosen edition; 自选 starts with all 正文 chapters ticked. Switching the sheet's language resets the checklist to that edition's chapters (block ids differ per edition). Presets 常用 / 全部分盘 / 仅核对表 and 全选 were retired with the redesign.
 - **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`. Chinese chart house lines use `SIGN_ZH`（白羊、金牛……，不带「座」）. English chart house lines keep the English sign name.
 
 - **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 labelled 「导出」 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.
-- **中文 / English (2026-09-29):** reports generated since the English edition carry both editions; the action bar shows segmented tabs (`.report-language-switch`, `aria-label="报告语言"`, 中文 / English, the same raised slot as the chart-type strip) before 「导出」. Reports without an English edition show no switch at all rather than a disabled one. The edition lives in the URL (`?lang=en`, read by the server page, written with `history.replaceState`), so refresh and shared links keep it. Switching remounts the article, TOC and fact tables for that edition and sets `lang` on the reader body; chrome (header, rail, 到底部) stays Chinese. Charts draw the same glyphs; only the legend reads `Su Mo …` / 「bar = retrograde」.

A report without an English edition still raises one info toast (id `report-export-english`) when the sheet opens. Switching the sheet's language still resets the checklist to that edition's blocks; the file name still gains `-EN`.
 - **Opening a report (2026-09-30, BUG-1106):** one waiting screen, `ReportOpening` — the 46px header 「个人报告」 over a centred spinner and 「正在加载报告…」. The route's `loading.tsx` and the reader's first fetch both render it, so nothing swaps or jumps between them.
 - **Phones (2026-09-30, BUG-1107):** the action bar is one row, about 53px: an arrow-only back link (screen readers still hear 「返回报告中心」), the 中文 / English pill at 36px segments, and 「导出」 at 40px. In the export sheet below 767px the sheet slides up from the bottom and may take up to 85dvh. There is no description line and no file size. 关闭 is a × icon (accessible name 「关闭导出」).
