   /cool/ — cinematic box film. LOADED ONLY ON /cool/.
   Moved out of assets/theme-scroll.css so the homepage never ships the rules
   that hide navigation or stretch the document to 340vh.

   Layer contract (do not reorder):
     1  .cool-page-media     canvas + poster
     2  .cool-page-overlay   vignette / glow, pointer-events:none
     3  .cool-page-content   headline + CTA
    10  .cool-page-controls  back / skip / beta — always reachable
