 * spans, and a yellow playhead. Bottom: the active event(s) as a badge plus
 * the full event list for the current segment.
 *
 * ## Data format
 * JSONL lines `{ ts: number, te: number, label: string, ...extras }`.
 * Events must stay inside their enclosing segment's `[startTime, endTime)`.
 *
 * ## Hooks used
 * `usePlaylist` (for segment boundaries & duration), `useSegment` (events of
 * the current chunk), `useClockValue` (playhead refresh).
