+## 🔧 文案提取助手修复 — 抖音链接无法提取文案 (Day 25)
+
+### 概述
+
+文案提取助手粘贴抖音链接后无法提取文案，yt-dlp 报错 `Fresh cookies are needed`，手动回退方案也因抖音页面结构变化失效。本日完成了完整修复，并清理了不再需要的 `DOUYIN_COOKIE` 配置。
+
+---
+
+## 🐛 问题诊断
+
+### 错误链路
+
+1. **yt-dlp 失败**：`ERROR: [Douyin] Fresh cookies (not necessarily logged in) are needed`
+   - yt-dlp 版本 `2025.12.08` 过旧
+   - 抖音 API `aweme/v1/web/aweme/detail/` 需要签名 cookie（`s_v_web_id` 等），即使升级 yt-dlp 到最新版 + 传入 cookie 仍无法解决，属 yt-dlp 已知问题
+2. **手动回退失败**：`Could not find RENDER_DATA in page`
+   - 旧方案通过桌面端用户主页 + `modal_id` 访问，抖音 SSR 已不再返回 `videoDetail` 数据
+3. **`.env` 中 `DOUYIN_COOKIE`**：时间戳 2024 年 12 月，早已过期
+
+---
+
+## ✅ 修复方案：移动端分享页 + 自动获取 ttwid
+
+### 核心思路
+
+放弃依赖 yt-dlp 下载抖音视频和手动维护 cookie，改为：
+
+1. 自动从 ByteDance 公共 API 获取新鲜 `ttwid`（匿名令牌，不绑定账号）
+2. 用 `ttwid` 访问移动端分享页 `m.douyin.com/share/video/{id}`
+3. 从页面内嵌 JSON 中提取 `play_addr` 播放地址并下载
+
+### 关键代码（`_download_douyin_manual` 重写）
+
+```python
+# 1. 获取新鲜 ttwid
+ttwid_resp = await client.post(
+    "https://ttwid.bytedance.com/ttwid/union/register/",
+    json={"region": "cn", "aid": 6383, "service": "www.douyin.com", ...}
+)
+ttwid = ttwid_resp.cookies.get("ttwid", "")
+
+# 2. 访问移动端分享页
+page_resp = await client.get(
+    f"https://m.douyin.com/share/video/{video_id}",
+    headers={"cookie": f"ttwid={ttwid}", ...}
+)
+
+# 3. 提取 play_addr
+addr_match = re.search(r'"play_addr":\{"uri":"([^"]+)","url_list":\["([^"]+)"', page_text)
+video_url = addr_match.group(2).replace(r"\u002F", "/")
+```
+
+### 优势
+
+- 不再依赖手动维护的 `DOUYIN_COOKIE`，ttwid 每次请求自动获取
+- 不受 yt-dlp 对抖音支持状况影响
+- 所有用户通用，不绑定特定账号
+
+---
+
+## 🧹 清理 DOUYIN_COOKIE 配置
+
+`DOUYIN_COOKIE` 仅用于文案提取，新方案不再需要，已从以下位置删除：
+
+| 文件 | 变更 |
+|------|------|
+| `backend/.env` | 删除 `DOUYIN_COOKIE` 配置项及注释 |
+| `backend/app/core/config.py` | 删除 `DOUYIN_COOKIE: str = ""` 字段定义 |
+| `backend/app/modules/tools/service.py` | 删除 yt-dlp 传 cookie 逻辑和 `_write_netscape_cookies` 辅助函数 |
+
+---
+
+## 🔤 前端文案修正
+
+将文案提取界面中的"AI 洗稿结果"改为"AI 改写结果"。
+
+| 文件 | 变更 |
+|------|------|
+| `frontend/src/features/home/ui/ScriptExtractionModal.tsx` | `AI 洗稿结果` → `AI 改写结果` |
+| `backend/app/modules/tools/service.py` | 注释中"洗稿"→"改写" |
+| `backend/app/services/glm_service.py` | docstring 中"洗稿"→"改写文案" |
+
+---
+
+## 📦 其他变更
+
+- **yt-dlp 升级**：`2025.12.08` → `2026.2.21`
+- **yt-dlp 初始化修正**：改为 `YoutubeDL(ydl_opts)` 直接传参初始化（原先空初始化后 update params 不生效）
+- **User-Agent 更新**：yt-dlp 中 `Chrome/91` → `Chrome/131`
+
+---

+
+## ✏️ AI 智能改写 — 自定义提示词功能
+
+### 概述
+
+文案提取助手的"AI 智能改写"原先使用硬编码 prompt，用户无法定制改写风格。本次在 checkbox 右侧新增"自定义提示词"折叠区域，用户可编辑自定义 prompt，持久化到 localStorage，后端按需替换默认 prompt。
+
+### 后端修改
+
+**路由层** (`router.py`)：`extract_script_tool` 新增可选 Form 参数 `custom_prompt: Optional[str] = Form(None)`，透传给 service。
+
+**服务层** (`service.py`)：`extract_script()` 签名新增 `custom_prompt`，透传给 `glm_service.rewrite_script(script, custom_prompt)`。
+
+**AI 层** (`glm_service.py`)：`rewrite_script(self, text, custom_prompt=None)`，若 `custom_prompt` 有值则用自定义 prompt + 原文拼接，否则保持原有默认 prompt。
+
+```python
+if custom_prompt and custom_prompt.strip():
+    prompt = f"""{custom_prompt.strip()}
+
+原始文案：
+{text}"""
+else:
+    prompt = f"""请将以下视频文案进行改写。...（原有默认）"""
+```
+
+### 前端修改
+
+**Hook** (`useScriptExtraction.ts`)：
+- 新增 `customPrompt` / `showCustomPrompt` 状态
+- 初始值从 `localStorage.getItem("vigent_rewriteCustomPrompt")` 恢复
+- `customPrompt` 变化时防抖 300ms 保存到 localStorage
+- `handleExtract()` 中若 `doRewrite && customPrompt.trim()` 有值，追加 `formData.append("custom_prompt", ...)`
+- modal 重置时不清空 customPrompt（持久化偏好）
+
+**UI** (`ScriptExtractionModal.tsx`)：
+- checkbox 同行右侧新增"自定义提示词 ▼"按钮（仅 `doRewrite` 时显示）
+- 点击展开 textarea 编辑区域，底部提示"留空则使用默认提示词"
+- 取消勾选 AI 智能改写时，自定义提示词区域自动隐藏
+
+### 涉及文件
+
+| 文件 | 变更 |
+|------|------|
+| `backend/app/modules/tools/router.py` | 新增 `custom_prompt` Form 参数 |
+| `backend/app/modules/tools/service.py` | `extract_script()` 透传 `custom_prompt` |
+| `backend/app/services/glm_service.py` | `rewrite_script()` 支持自定义 prompt |
+| `frontend/.../useScriptExtraction.ts` | 新增状态、localStorage 持久化、FormData 传参 |
+| `frontend/.../ScriptExtractionModal.tsx` | UI 按钮 + 展开 textarea |
+
+### 验证
+
+- 后端 `python -m py_compile` 三个文件通过
+- 前端 `npx tsc --noEmit` 通过
+
+---
+
+## 🐛 SSR 构建修复 — localStorage is not defined
+
+### 问题
+
+`npm run build` 报错 `ReferenceError: localStorage is not defined`，因为 `useScriptExtraction.ts` 中 `useState` 的初始化函数在 SSR（Node.js）环境下也会执行，而服务端没有 `localStorage`。
+
+### 修复
+
+`useState` 初始化加 `typeof window !== "undefined"` 守卫：
+
+```typescript
+const [customPrompt, setCustomPrompt] = useState(
+    () => typeof window !== "undefined" ? localStorage.getItem(CUSTOM_PROMPT_KEY) || "" : ""
+);
+```
+
+| 文件 | 变更 |
+|------|------|
+| `frontend/.../useScriptExtraction.ts` | `useState` 初始化增加 SSR 安全守卫 |
+
+---
+
+## 🎬 片头副标题功能
+
+### 概述
+
+新增片头副标题（secondary_title），显示在主标题下方，用于补充说明或悬念引导。副标题有独立的样式配置（字体、字号、颜色等），可由 AI 同时生成，20 字限制，仅在视频画面中显示，不参与发布标题。
+
+命名约定：后端 `secondary_title`（snake_case），前端 `videoSecondaryTitle`（camelCase），用户界面"片头副标题"。
+
+---
+
+### 后端修改
+
+| 文件 | 变更 |
+|------|------|
+| `backend/app/modules/videos/schemas.py` | `GenerateRequest` 新增 4 个可选字段：`secondary_title`、`secondary_title_style_id`、`secondary_title_font_size`、`secondary_title_top_margin` |
+| `backend/app/services/glm_service.py` | AI prompt 增加副标题生成要求（不超过20字），JSON 格式新增 `secondary_title` 字段 |
+| `backend/app/modules/ai/router.py` | `GenerateMetaResponse` 增加 `secondary_title: str = ""`，endpoint 返回时取 `result.get("secondary_title", "")` |
+| `backend/app/modules/videos/workflow.py` | `use_remotion` 条件增加 `or req.secondary_title`；副标题样式解析复用 `get_style("title", ...)`；字号/间距覆盖；`prepare_style_for_remotion` 处理副标题字体；`remotion_service.render()` 传入 `secondary_title` + `secondary_title_style` |
+| `backend/app/services/remotion_service.py` | `render()` 新增 `secondary_title` 和 `secondary_title_style` 参数，构建 CLI 参数 `--secondaryTitle` 和 `--secondaryTitleStyle` |
+
+### Remotion 修改
+
+| 文件 | 变更 |
+|------|------|
+| `remotion/render.ts` | `RenderOptions` 新增 `secondaryTitle?` + `secondaryTitleStyle?`；`parseArgs()` 新增 switch case；`inputProps` 新增两个字段 |
+| `remotion/src/components/Title.tsx` | `TitleProps` 新增 `secondaryTitle?` 和 `secondaryTitleStyle?`；`AbsoluteFill` 改为 `flexDirection: 'column'` 垂直堆叠；主标题 `<h1>` 后增加副标题 `<h2>`，独立样式（默认字号 48px、字重 700），共享淡入淡出动画；副标题字体使用独立 `@font-face`（`SecondaryTitleFont`）避免与主标题冲突 |
+| `remotion/src/Video.tsx` | `VideoProps` 新增 `secondaryTitle?` + `secondaryTitleStyle?`；传递给 `<Title>` 组件；渲染条件改为 `{(title \|\| secondaryTitle) && ...}` |
+| `remotion/src/Root.tsx` | `defaultProps` 新增 `secondaryTitle: undefined` + `secondaryTitleStyle: undefined` |
+
+### 前端修改
+
+| 文件 | 变更 |
+|------|------|
+| `frontend/src/shared/lib/title.ts` | 新增 `SECONDARY_TITLE_MAX_LENGTH = 20` 和 `clampSecondaryTitle()` |
+| `frontend/src/features/home/model/useHomeController.ts` | 新增状态 `videoSecondaryTitle`、`selectedSecondaryTitleStyleId`、`secondaryTitleFontSize`、`secondaryTitleTopMargin`、`secondaryTitleSizeLocked`；新建 `secondaryTitleInput = useTitleInput({ maxLength: 20 })`（不 sync 到发布页）；`handleGenerateMeta()` 接收并填充 `secondary_title`；`handleGenerate()` 构建 payload 增加副标题字段；return 暴露所有新状态 |
+| `frontend/src/features/home/model/useHomePersistence.ts` | 新增 localStorage key：`secondaryTitle`、`secondaryTitleStyle`、`secondaryTitleFontSize`、`secondaryTitleTopMargin`；对应的恢复和保存 effect |
+| `frontend/src/features/home/ui/TitleSubtitlePanel.tsx` | Props 新增副标题相关；主标题输入框下方添加"片头副标题（限制20个字）"输入框；副标题样式选择器（复用 titleStyles 预设）、字号滑块（30-100px）、间距滑块（0-100px） |
+| `frontend/src/features/home/ui/FloatingStylePreview.tsx` | 标题预览改为 flex column 布局；主标题下方增加副标题预览行，独立样式渲染 |
+| `frontend/src/features/home/ui/HomePage.tsx` | 从 `useHomeController` 解构新状态，传给 `TitleSubtitlePanel` |
+

+
+## 🐛 参考音频上传 — 中文文件名 InvalidKey 修复
+
+### 问题
+
+上传中文名参考音频（如"我的声音.wav"）时，Supabase Storage 报 `InvalidKey`，因为存储路径直接使用了原始中文文件名。
+
+### 修复
+
+在 `ref_audios/service.py` 新增 `sanitize_filename()` 函数，将存储路径的文件名清洗为 ASCII 安全字符（仅 `A-Za-z0-9._-`）：
+
+- NFKD 规范化 → 丢弃非 ASCII → 非法字符替换为 `_`
+- 纯中文/emoji 清洗后为空时，使用 MD5 哈希兜底（如 `audio_e924b1193007`）
+- 文件名限长 50 字符
+- 原始中文文件名保留在 metadata 中作为展示名，前端显示不受影响
+
+```
+修复前: cbbe.../1771915755_我的声音.wav  → InvalidKey
+修复后: cbbe.../1771915755_audio_xxxxxxxx.wav → 上传成功
+```
+
+| 文件 | 变更 |
+|------|------|
+| `backend/app/modules/ref_audios/service.py` | 新增 `sanitize_filename()` 函数，上传路径使用清洗后文件名 |

+## 🎨 前端优化：板块合并 + 序号标题 + UI 精细化 (Day 26)
+
+### 概述
+
+首页原有 9 个独立板块（左栏 7 个 + 右栏 2 个），每个都有自己的卡片容器和标题，视觉碎片化严重。本次将相关板块合并为 5 个主板块，添加中文序号（一~十），移除 emoji 图标，并对多个子组件的布局和交互细节进行优化。
+
+---
+
+## ✅ 改动内容
+
+### 1. 板块合并方案
+
+**左栏（4 个主板块 + 2 个独立区域）：**
+
+| 序号 | 板块名 | 子板块 | 原组件 |
+|------|--------|--------|--------|
+| 一 | 文案提取与编辑 | — | ScriptEditor |
+| 二 | 标题与字幕 | — | TitleSubtitlePanel |
+| 三 | 配音 | 配音方式 / 配音列表 | VoiceSelector + GeneratedAudiosPanel |
+| 四 | 素材编辑 | 视频素材 / 时间轴编辑 | MaterialSelector + TimelineEditor |
+| 五 | 背景音乐 | — | BgmPanel |
+| — | 生成按钮 | — | GenerateActionBar（不编号） |
+
+**右栏（1 个主板块）：**
+
+| 序号 | 板块名 | 子板块 | 原组件 |
+|------|--------|--------|--------|
+| 六 | 作品 | 作品列表 / 作品预览 | HistoryList + PreviewPanel |
+
+**发布页（/publish）：**
+
+| 序号 | 板块名 |
+|------|--------|
+| 七 | 平台账号 |
+| 八 | 选择发布作品 |
+| 九 | 发布信息 |
+| 十 | 选择发布平台 |
+
+### 2. embedded 模式
+
+6 个组件新增 `embedded?: boolean` prop（默认 `false`）：
+
+- `VoiceSelector` — embedded 时不渲染外层卡片和主标题
+- `GeneratedAudiosPanel` — embedded 时两行布局：第 1 行（语速+生成配音右对齐）、第 2 行（配音列表+刷新）
+- `MaterialSelector` — embedded 时自渲染 h3 子标题"视频素材"+ 上传/刷新按钮同行
+- `TimelineEditor` — embedded 时自渲染 h3 子标题"时间轴编辑"+ 画面比例/播放控件同行
+- `PreviewPanel` — embedded 时不渲染外层卡片和标题
+- `HistoryList` — embedded 时不渲染外层卡片和标题（刷新按钮由 HomePage 提供）
+
+### 3. 序号标题 + emoji 移除
+
+所有编号板块移除 emoji 图标，使用纯中文序号：
+
+- ScriptEditor: `✍️ 文案提取与编辑` → `一、文案提取与编辑`
+- TitleSubtitlePanel: `🎬 标题与字幕` → `二、标题与字幕`
+- BgmPanel: `🎵 背景音乐` → `五、背景音乐`
+- HomePage 右栏: `五、作品` → `六、作品`
+- PublishPage: `👤 平台账号` → `七、平台账号`、`📹 选择发布作品` → `八、选择发布作品`、`✍️ 发布信息` → `九、发布信息`、`📱 选择发布平台` → `十、选择发布平台`
+
+### 4. 子标题与分隔样式
+
+- **主标题**: `text-base sm:text-lg font-semibold text-white`
+- **子标题**: `text-sm font-medium text-gray-400`
+- **分隔线**: `<div className="border-t border-white/10 my-4" />`
+
+### 5. 配音列表布局优化
+
+GeneratedAudiosPanel embedded 模式下采用两行布局：
+- **第 1 行**：语速下拉 + 生成配音按钮（右对齐，`flex justify-end`）
+- **第 2 行**：`<h3>配音列表</h3>` + 刷新按钮（两端对齐）
+- 非 embedded 模式保持原单行布局
+
+### 6. TitleSubtitlePanel 下拉对齐
+
+- 标题样式/副标题样式/字幕样式三行标签统一 `w-20`（固定 80px），确保下拉菜单垂直对齐
+- 下拉菜单宽度 `w-1/3 min-w-[100px]`，避免过宽
+
+### 7. RefAudioPanel 文案简化
+
+- 原底部段落"上传任意语音样本（3-10秒）…" 移至 "我的参考音频" 标题旁，简化为 `(上传3-10秒语音样本)`
+
+### 8. 账户下拉菜单添加手机号
+
+- AccountSettingsDropdown 在账户有效期上方新增手机号显示区域
+- 显示 `user?.phone || '未知账户'`
+
+### 9. 标题显示模式对副标题生效
+
+- **payload 修复**: `useHomeController.ts` 中 `title_display_mode` 的发送条件从 `videoTitle.trim()` 改为 `videoTitle.trim() || videoSecondaryTitle.trim()`，确保仅有副标题时也能发送显示模式
+- **UI 调整**: 短暂显示/常驻显示下拉从片头标题输入行移至"二、标题与字幕"板块标题行（与预览样式按钮同行），明确表示该设置对标题和副标题同时生效
+- Remotion 端 `Title.tsx` 已支持（标题和副标题作为整体组件渲染，`displayMode` 统一控制）
+
+### 10. 时间轴模糊遮罩
+
+遮罩从外层 wrapper 移入"四、素材编辑"卡片内，仅覆盖时间轴子区域（`rounded-xl`）。
+
+### 11. 登录后用户信息立即可用
+
+- AuthContext 新增 `setUser` 方法暴露给消费者
+- 登录页成功后调用 `setUser(result.user)` 立即写入 Context，无需等页面刷新
+- 修复登录后账户下拉显示"未知账户"、刷新后才显示手机号的问题
+
+### 12. 文案与选项微调
+
+- MaterialSelector 描述 `(可多选，最多4个)` → `(上传自拍视频，最多可选4个)`
+- TitleSubtitlePanel 显示模式选项 `短暂显示/常驻显示` → `标题短暂显示/标题常驻显示`
+
+### 13. UI/UX 体验优化（6 项）
+
+- **操作按钮移动端可见**: 配音列表、作品列表、素材列表、参考音频、历史文案的操作按钮从 `opacity-0`（hover 才显示）改为 `opacity-40`（平时半透明可见，hover 全亮），解决触屏设备无法发现按钮的问题
+- **手机号脱敏**: AccountSettingsDropdown 手机号中间四位遮掩 `138****5678`
+- **标题字数计数器**: TitleSubtitlePanel 标题/副标题输入框右侧显示实时字数 `3/15`，超限变红
+- **列表滚动条提示**: ~~配音列表、作品列表、素材列表、BGM 列表从 `hide-scrollbar` 改为 `custom-scrollbar`~~ → 已全部改回 `hide-scrollbar` 隐藏滚动条（滚动功能不变）
+- **时间轴拖拽提示**: TimelineEditor 色块左上角新增 `GripVertical` 抓手图标，暗示可拖拽排序
+- **截取滑块放大**: ClipTrimmer 手柄从 16px 放大到 20px，触控区从 32px 放大到 40px
+
+### 14. 代码质量修复（4 项）
+
+- **AccountSettingsDropdown**: 关闭密码弹窗补齐 `setSuccess('')` 清空
+- **MaterialSelector**: `selectedSet` 加 `useMemo` 避免每次渲染重建
+- **TimelineEditor**: `visibleSegments`/`overflowSegments` 加 `useMemo`
+- **MaterialSelector**: 素材满 4 个时非选中项按钮加 `disabled`
+
+### 15. 发布页平台账号响应式布局
+
+- **单行布局**：图标+名称+状态在左，按钮在右（`flex items-center`）
+- **移动端紧凑**：图标 `h-6 w-6`、按钮 `text-xs px-2 py-1 rounded-md`、间距 `space-y-2 px-3 py-2.5`
+- **桌面端宽松**：`sm:h-7 sm:w-7`、`sm:text-sm sm:px-3 sm:py-1.5 sm:rounded-lg`、`sm:space-y-3 sm:px-4 sm:py-3.5`
+- 两端各自美观，风格与其他板块一致
+
+### 16. 移动端刷新回顶部修复
+
+- **问题**: 移动端刷新页面后不回到顶部，而是滚动到背景音乐板块
+- **根因**: 1) 浏览器原生滚动恢复覆盖 `scrollTo(0,0)`；2) 列表 scroll effect 有双依赖（`selectedId` + `list`），数据异步加载时第二次触发跳过了 ref 守卫，执行了 `scrollIntoView` 导致页面跳动
+- **修复**: 三管齐下 — ① `history.scrollRestoration = "manual"` 禁用浏览器原生恢复；② 时间门控 `scrollEffectsEnabled` ref（1 秒内禁止所有列表自动滚动）替代单次 ref 守卫；③ 200ms 延迟兜底 `scrollTo(0,0)`
+
+### 17. 移动端样式预览窗口缩小
+
+- **问题**: 移动端点击"预览样式"后窗口占满整屏（宽 358px，高约 636px），遮挡样式调节控件
+- **修复**: 移动端宽度从 `window.innerWidth - 32` 缩小到 **160px**；位置从左上角改为**右下角**（`right:12, bottom:12`），不遮挡上方控件；最大高度限制 `50dvh`
+- 桌面端保持不变（280px，左上角）
+
+### 18. 列表滚动条统一隐藏
+
+- 将 Day 26 早期改为 `custom-scrollbar`（细紫色滚动条）的 7 处全部改回 `hide-scrollbar`
+- 涉及：BgmPanel、GeneratedAudiosPanel、HistoryList、MaterialSelector（2处）、ScriptExtractionModal（2处）
+- 滚动功能不受影响，仅视觉上不显示滚动条
+
+### 19. 配音按钮移动端适配
+
+- VoiceSelector "选择声音/克隆声音" 按钮：内边距 `px-4` → `px-2 sm:px-4`，字号加 `text-sm sm:text-base`，图标加 `shrink-0`
+- 修复移动端窄屏下按钮被挤压导致"克隆声音"不可见的问题
+
+### 20. 素材标题溢出修复
+
+- MaterialSelector embedded 标题行移除 `whitespace-nowrap`
+- 描述文字 `(上传自拍视频，最多可选4个)` 在移动端隐藏（`hidden sm:inline`），桌面端正常显示
+- 修复移动端刷新按钮被推出容器外的问题
+
+### 21. 生成配音按钮放大
+
+- "生成配音" 作为核心操作按钮，从辅助尺寸升级为主操作尺寸
+- 内边距 `px-2/px-3 py-1/py-1.5` → `px-4 py-2`，字号 `text-xs` → `text-sm font-medium`
+- 图标 `h-3.5 w-3.5` → `h-4 w-4`，新增 `shadow-sm` + hover `shadow-md`
+- embedded 与非 embedded 模式统一放大
+
+### 22. 生成进度条位置调整
+
+- **问题**: 生成进度条在"六、作品"卡片内部（作品预览下方），不够醒目
+- **修复**: 进度条从 PreviewPanel 内部提取到 HomePage 右栏，作为独立卡片渲染在"六、作品"卡片**上方**
+- 使用紫色边框（`border-purple-500/30`）区分，显示任务消息和百分比
+- PreviewPanel embedded 模式下不再渲染进度条（传入 `currentTask={null}`）
+- 生成完成后进度卡片自动消失
+
+### 23. LatentSync 超时修复
+
+- **问题**: 约 2 分钟的视频（3023 帧，190 段推理）预计推理 54 分钟，但 httpx 超时仅 20 分钟，导致 LatentSync 调用失败并回退到无口型同步
+- **根因**: `lipsync_service.py` 中 `httpx.AsyncClient(timeout=1200.0)` 不足以覆盖长视频推理时间
+- **修复**: 超时从 `1200s`（20 分钟）改为 `3600s`（1 小时），足以覆盖 2-3 分钟视频的推理
+
+### 24. 字幕时间戳节奏映射（修复长视频字幕漂移）
+
+- **问题**: 2 分钟视频字幕明显对不上语音，越到后面偏差越大
+- **根因**: `whisper_service.py` 的 `original_text` 处理逻辑丢弃了 Whisper 逐词时间戳，仅保留总时间范围后做全程线性插值，每个字分配相同时长，完全忽略语速变化和停顿
+- **修复**: 保留 Whisper 的逐字时间戳作为语音节奏模板，将原文字符按比例映射到 Whisper 时间节奏上（rhythm-mapping），而非线性均分。字幕文字不变，只是时间戳跟随真实语速
+- **算法**: 原文第 i 个字符映射到 Whisper 时间线的 `(i/N)*M` 位置（N=原文字符数，M=Whisper字符数），在相邻 Whisper 时间点间线性插值
