   overview_film.css — the front-page overview film (index.html #overview)
   A 1280x720 stage scaled to fit. Every animation is paused here and driven by
   overview_film.js from the narration clock (animation.currentTime), so picture,
   voice, captions and cues stay in step, and any frame can be rendered by seek().
   Beat times (--b-*) are set per scene from media/overview/overview_timeline.json;
   the defaults below match the current bake.
   Interface content is SAMPLE DATA. No real students, staff or institutions.
