/* Motion policy.

   A scroll-scrubbed flight is continuous camera motion, so the reduced-motion
   branch is a floor here, not a nicety. With it on, film-scrub.js never fetches
   the clip and the stage keeps its poster: the composition, the wash, and every
   word survive — only the camera stops. */
