// The enriched Plex detail page. Covers the TMDB-fed pieces added on the page variant — the
// multi-source ratings row (IMDb / TMDb / audience), the facts panel (budget / revenue / studios /
// countries), the keyword chips (→ onFilter), and the full crew (→ onOpenPerson). i18n is
// key-passthrough; PlexInfo is prop-driven (no queries) so it just needs a QueryClient for its cache
// reads. The overlay variant is asserted to stay lean (no facts/keywords/crew).
