/*
 * Marquee block — continuous horizontal card strips.
 *
 * The drift is a CSS keyframe animation (translateX to -50% on a track that
 * holds TWO identical card sets), so the loop runs on the compositor and its
 * wrap is seamless with no main-thread jump. (The shared JS carousel engine
 * drove it before, but its per-loop transform jump flashed the whole row.)
 * Per-instance values (card width, gap, padding, fade width, row gap, type
 * sizes; plus the animation duration/direction inline) arrive from
 * includes/element-renderers/marquee.php.
