   - Desktop (mouse wheel) is driven by JS in main.js — one wheel gesture

     fights it; JS gives true one-gesture-per-page motion instead.
   - Touch devices use the native CSS proximity snap, which rides swipe
     momentum. Only the full-screen video sections lock; the taller menu
     and reserve sections scroll freely and hand off at their edges. */
