/**
 * Variant CSS: video--cinematic-stacked
 *
 * A centred editorial intro above a wide cinematic 21:9 poster with a CSS play
 * button, caption beneath. The text lives in its own clean block (not overlaid
 * on the frame). Poster image + CSS-only play disc — no iframe, no autoplay, no
 * JS. Text stays --ink (polarity-aware); the play disc uses the text-on-photo
 * pattern (accent fill + white ring + dark halo) so it reads on any frame.
