   The collapse is SCRUBBED against scroll position on the compositor — it follows
   the scroll exactly (like the original) but stays smooth because JS never drives
   it per frame. JS only publishes each element's --from/--to (and --clip-*)
   endpoints; these keyframes interpolate between them over the first ~70vh of
   scroll, so the motion fills the hero rather than triggering all at once. */
