/* Visual Threshold — cinematic scroll story.
   Geometry, transforms and choreography values are unchanged from the original
   rig; only palette, typography and edge treatment carry the eyewear theme.
   Scene-layer class names keep their original scaffold names so they stay in
   lockstep with the custom properties the engine writes:
     .back-four  -> chrome highlight layer      .bridge-img -> hero still
     .back-bazaar-> layout wall                 .frame-two-img -> macro reveal
     .story-panel-bridge -> frame beat          .story-panel-bazaar -> collection beat */
