/*
 * SoulSync — Video Watchlist page (isolated).
 *
 * The shows + people you follow, split by a Shows / People tab switcher. Reads
 * /api/video/watchlist; cards reuse the shared VideoWatchlist eye-button (here it
 * reads as "watched" and un-follows on click). v1 is membership only — the
 * monitoring/discovery engine that turns follows into downloads comes later.
