/**
 * CoverflowCarousel — vijf kaarten in een 3D-waaier: de middelste recht en
 * scherp met tekst en een knop erop, de buren gedraaid, kleiner en donkerder;
 * de achtergrond is de foto in focus, vaag en donker. Pijlen, stippen,
 * pijltjestoetsen (als de carrousel focus heeft), swipe en autoplay.
 *
 * De bron had `transition: all 800ms cubic-bezier(…)` en een vast palet
 * (#0c0a09, #c5a880 goud, witte tekst met rgba-schaduwen). Hier: per
 * property (transform, opacity, filter) met het smooth-token, goud →
 * --primary, alles via tokens en color-mix; vaste 285/510px-offsets →
 * verhoudingen van de kaartbreedte (CSS-variabele). Toetsen luisteren op het
 * element, niet op window.
