   Operant Learner · slide stage + Theater player            css/ol-stage.css
   --------------------------------------------------------------------------
   Board #385 (2026-10-05): slides are an interactive video. The slide is a
   fixed 1280x720 logical canvas scaled uniformly by js/ol-stage.js; nothing
   inside it scrolls. Loaded by index.html (after ol-portal.css) and by
   review-studio.html, so the studio shows exactly the learner's frame.

   Sections
     1. Stage + canvas            (shared: portal + studio)
     2. Type floor on the canvas  (shared)
     3. Theater layout            (portal: body.ol-theater)
     4. Course bar + control bar  (portal)
     5. Immersive: full screen and phone landscape
     6. Phone portrait: readable reflow
