- * 智能剪辑页面 — 服务器渲染预览架构
+ * 智能剪辑页面 — 前端实时预览架构
  * 7 步向导：选择模板 → 素材 → 配音 → 标题 → 预览 → 封面 → 确认生成
  * 左右布局：左侧 generate-form + 右侧 generate-preview
  *
  * 架构：
- * - Step4+ 右侧预览面板自动创建服务器预览渲染任务（POST /generation/preview）
- * - 轮询完成后播放服务器渲染的真实视频（<video> 标签）
- * - 标题样式编辑时 CSS 层实时叠加预览
- * - 素材/配音/BGM 变更自动重新渲染；标题变更标记 stale
- * - 点"确认生成"时走 confirm 路径，成品就是预览视频本身，100% 一致
+ * - Step4+ 右侧预览面板使用 FrontendPreviewPlayer 实时播放素材片段
+ * - 标题样式编辑时 CSS 层实时叠加预览，所见即所得
+ * - 点"确认生成"时调用 createGenerationTask 创建一次服务器渲染任务
