// a card's "i" button (variant="page", with a big Play/Resume + watch controls), and a lean overlay
// over the running player (variant="overlay", opened with "i"). Two GUI elements are user-toggleable
// personal preferences, persisted in users.preferences: the faint art backdrop and the cast row.
// The TMDB-enriched pieces (multi-source ratings row, facts, keyword chips, full crew — E5 S5) render
// on the page variant only; the overlay stays lean.

// USD — TMDB budget/revenue figures are USD regardless of the viewer's language.
