   SCENES — paged, full-viewport navigation (replaces native cross-page
   scrolling entirely; see navigation.js for the controller).

   Every `.scene` is an independently scrollable 100dvh viewport, absolutely
   stacked on the others. Only the one carrying `.is-active` is visible and
   interactive — navigation.js is the single source of truth for which that
   is, and drives the cinematic curtain when it changes. There is no native
   scroll *between* scenes any more (html/body are locked below).

   A scene taller than one viewport — the opening hero+showcase+marquee
   scene, and the closing contact+footer scene — still scrolls normally
   *inside itself* exactly as it always did; navigation.js only advances to
   the next/previous scene once that internal scroll reaches its start or
   end edge, so nothing inside them had to change.
