-/**
- * 水平轨道时间线 — 支持裁剪手柄、分割、右键菜单
- * 时间标尺 + 片段轨道 + HTML5拖拽排序
- *
- * 子组件（timeline/）：
- * - TimeRuler - 时间标尺
- * - ClipCard - 片段卡片
- * - ClipTrack - 片段轨道（播放头+片段列表+添加卡片）
- * - TimelineHeader - 时间线头部（标题+缩放+操作按钮）
- * - TrimPreview - 裁剪预览 tooltip
- * - ContextMenu - 右键菜单
- *
- * Hooks：
- * - useClipDrag - 片段拖拽排序
- * - useTrimDrag - 裁剪拖拽
- * - useTimelineMenus - 菜单 & 面板
- * - usePlayheadDrag - 播放头拖拽
