Frontend drops 15 files no page reaches (issue #139, BUG-1480)

Unreachable from every app entry and frontend/scripts (dynamic imports
counted): chart-basics-tab, error-toast, seven unused shadcn ui files
(skeleton among them), three birth-time helpers only tests used, the motion
provider shell (it imported motion/react statically), and the two empty
people/account stores. Tests that only exercised them are removed or trimmed,
each with old/new/reason notes. Unreachable files 18 -> 3 (all kept on
purpose); npm test names drop exactly the 4 removed and 1 renamed test.

 # 印度占星 Skill 更新日志
 
+## 2026-10-28 — 前端删掉 15 个没人用的文件
+
+- 删掉 15 个没有任何页面用到的前端文件（约 700 行），其中包括一个会把动效库带回首屏的旧外壳和一个与「不出现骨架屏」规定冲突的组件。用户看到的内容不变。
+- Skill 版本不变（BUG-1480，issue #139）。
+
 ## 2026-10-28 — VedAstro 限流或不可用时，不再每轮重等
 
 - VedAstro 被限流或暂时拿不到数据时，同一张盘当天只问一次；之后的提问直接说明「外部校验暂不可用」，不再每轮多等 0.4～1.5 秒。第二天会重新问。

+## BUG-1480 | 前端留着 15 个没有任何页面用到的文件
+
+- 状态：resolved（代码 + 回归测试；待部署）
+- 首次发现 / 最近更新：2026-10-28 / 2026-10-28（issue #118 代码体检第 24 条 → #139）
+- 影响面：`frontend/src/`；不影响任何页面（这些文件从任何入口都不可达）。
+- 现象：从所有页面、布局、接口、错误页入口和 `frontend/scripts/` 出发（计入动态 import），有 18 个文件不可达。其中 `lib/motion/provider.tsx` 静态引用 `motion/react`，将来谁一引用 Motion 就回到首屏；`ui/skeleton` 与 DESIGN「揭幕后不得出现骨架」冲突，留着容易被误用。
+- 根因：改版和组件库生成后留下的残余，只被测试引用或没人引用。
+- 修复：删除 15 个：`components/chart-page/chart-basics-tab.tsx`、`components/error-toast.tsx`、`components/ui/{avatar,empty,field,kbd,separator,skeleton,switch}.tsx`、`lib/birth-time-choice-question-model.ts`、`lib/birth-time-guided-terminal.ts`、`lib/birth-time-guided-turn-identity.ts`、`lib/motion/provider.tsx`、`stores/account-store.ts`、`stores/people-store.ts`。保留 `app/forbidden.tsx`（Next 的特殊入口文件）以及进度记录里写过理由的 `reader-appendix-language.ts`、`personal-report-longform-download.ts`。删前对每个文件用 `git grep -- tests/ frontend/` 核对，Python 源码契约测试里没有引用。
+- 测试变化（只少被删模块的用例）：删除 `birth-time-guide-flow.test.ts`（1 条，只测 `guidedTurnIdentity`）；`birth-time-choice-question.test.ts` 删 2 条（click intent submits primary and unknown options immediately、unmatched requests clarification without creating scoring evidence）；`birth-time-guided-review-fixes.test.ts` 删 1 条（dynamic medium terminal preserves its candidate range without direct adoption），另 1 条去掉 `guidedTerminalPath` 断言；`birth-time-rectification-contract.test.ts` 1 条去掉 `guidedTerminalPath` 断言；`ui-kit-stores.test.ts` 去掉两个空骨架 store 的断言（Home 不引用它们的断言保留）；`motion-presets.test.ts`「LazyMotion loads domAnimation asynchronously and honors reduced motion」改名为「the home and the layout never import motion or a motion shell statically」，只留首页与 layout 的静态引用约束。改动处都写了原值 / 新值 / 原因。
+- 验证：不可达文件 18 → 3（上面保留的 3 个）。全量前端测试与 staging 逐条比对：少的名字正好是上面 4 条删除和 1 条改名，没有新增失败。tsc 0、lint 0 error。删的都是不可达文件，打包内容不变。
+- 防复发：删除前跑可达性检查并 `git grep -- tests/ frontend/`；只被测试引用的模块连同测试一起删。
+- 关联：前端死代码清理（frontend-dead-code 进度记录）。
