/* hero-reel — cinematic hero video + live typographic caption layer
 *
 * The mp4 carries picture only: no text is ever burned into the frame, because
 * burned-in Korean would be wrong for the other 15 locales and soft on hidpi.
 * Every word here is live DOM, so it stays vector-crisp and goes through the
 * normal data-i18n path.
 *
 * Token names are the ones both public/index.html and drumpath.css already
 * define (--accent-primary, --text-primary, --radius-xl, ...), so this file
 * themes itself to whichever page loads it.
