fix(ai-avatar): 端到端一致性修复(标题/封面/B-roll位置/B-roll时长)
修复5个问题:

1. 最终视频标题一致性
   - 后端 drawtext 默认 font_size 从 36 改为 28(对齐前端 DEFAULT_TITLE_CONFIG.size)
   - 后端 drawtext 默认 position 从 'top' 改为 'bottom'(对齐前端默认值)
   - 前端 contract.ts font_size fallback 从 36 改为 28

2. 封面与视频一致性
   - 渲染完成后自动用 output_cover_url 更新前端封面配置
   - 前端封面标题预览 fontSize 改用 size*0.55 缩放(与对口型预览对齐)
   - 封面默认阴影改为 none(与后端 drawtext 无 shadow 行为对齐)

3. B-roll 位置一致性
   - ModalBRollEditor 使用 lipsyncJob.script_text(TTS 时锁定的文案)
     而非 state.scriptText(用户可能已修改的文案)

4. B-roll 时长精确化
   - 后端 lipsync_tts.py 新增 _compute_sentence_timings():
     TTS 音频用 ffmpeg silencedetect 检测静音点,与句子边界对齐
   - 新增 sentence_timings JSON 字段到 LipsyncJobModel + Alembic migration
   - 前端 sentences.ts 不再做字数比例估算,改为接收后端精确时间戳
   - ModalBRollEditor 接收 sentenceTimings prop

5. 标题拖拽位置修复
   - PanelLipsyncPreview 拖拽标题发送百分比坐标(0-100) + position:'custom'
   - 后端 build_title_drawtext_filter 的 custom 位置改用 drawtext 表达式
     x=(w-text_w)*{pct_x} y=(h-text_h)*{pct_y}(百分比,与视频尺寸解耦)

文件变更:
- apps/api/app/tasks/lipsync_tts.py: 句子时间戳计算
- apps/api/app/schemas/lipsync.py: sentence_timings 字段
- packages/adapters/sqlalchemy_impl/models.py: sentence_timings 列
- packages/domain/video_filter_builder.py: 百分比坐标 + 默认值对齐
- alembic/versions/075_add_sentence_timings.py: 数据库迁移
- apps/web/src/pages/ai-avatar/types.ts: SentenceTiming + RenderJob.output_cover_url
- apps/web/src/pages/ai-avatar/utils/sentences.ts: 移除字数估算
- apps/web/src/pages/ai-avatar/utils/contract.ts: font_size 默认值
- apps/web/src/pages/ai-avatar/components/PanelLipsyncPreview.tsx: 拖拽百分比
- apps/web/src/pages/ai-avatar/components/PanelCoverAndGenerate.tsx: 标题缩放
- apps/web/src/pages/ai-avatar/components/ModalBRollEditor.tsx: 后端时间戳
- apps/web/src/pages/ai-avatar/AiAvatarPage.tsx: 封面更新 + 传参
- tests/unit/test_video_filter_builder.py: 测试更新

VITE_API_URL=http://localhost:8000

开发指南

添加新页面

  1. 在 src/pages/ 下创建页面组件
  2. 在 src/router/index.tsx 中添加路由
  3. 确保导出 Component 用于懒加载

添加新 API

  1. 在 src/api/ 下创建服务模块
  2. 定义 TypeScript 接口
  3. 使用 apiClient 发起请求

状态管理

使用 Zustand 创建 Store:

import { create } from "zustand"

interface MyStore {
  data: any
  setData: (data: any) => void
}

export const useMyStore = create<MyStore>((set) => ({
  data: null,
  setData: (data) => set({ data }),
}))

部署

# 构建
npm run build

# 产物在 dist/ 目录
