/*
 * SoulSync — Video Search page (isolated, in-app).
 *
 * Debounced multi-search via /api/video/search (movies / shows / people from
 * TMDB). Movie/show results link to the OWNED library detail when we already
 * have them (library_id), otherwise to the TMDB-backed detail. People open the
 * in-app person page. Everything stays inside SoulSync — no external links.
 *
 * Reuses the library card classes (.library-artist-card). Self-contained IIFE,
 * no globals, event-delegated, no inline handlers. Talks only to /api/video/*.
