/* ---- Hotspots. While the picture is paused every element the scenes marked with data-info

   (data-current, set by video/src/interactive/panel.tsx) breathes; found objects carry a
   small mark; an idle frame's unfound objects take one staggered breath (data-attract). The
   motion uses the individual `translate` / `scale` properties so the frame's own inline
   `transform` (Rise, Block, the Camera) is never touched. Nothing here reaches the renders:
   the MP4s never load this file, and nothing matches while `.stage.is-playing`. Outline
   widths are in frame pixels, drawn through the Player's scale. The scenes' full-frame SVGs
