   High-end panel-to-panel scroll choreography
   - Each snap panel reveals its content in a staged sequence

     with `backwards` fill, so hover & active transforms keep working
     once the intro has played.
   - The whole panel recedes slightly while off-screen (depth), and a
     scroll-linked parallax (--s3-rel, set per panel in JS) drifts the
     hero symbol for an organic, connected feel between screens.
