/* ==========================================================================
   MOTION LAYER + RHYTHM (v1)
   Added on top of the tokens above — nothing in the original sheet is
   rewritten. Colours and typeface are unchanged; this section only adjusts
   scale, spacing, hover states, and adds the reveal/parallax machinery.

   Reveal contract:
     - assets/motion.js adds `html.motion-ready`, and only then does the
       pre-reveal (hidden) state below apply. The page ships visible; hiding
       is something the motion layer opts into once it can undo it.
     - That script then adds `.is-in` per element, in the same task, so no
       frame is ever painted with content hidden and unresolved.
     - A reader without JS, a browser that drops `:is()`, reduced motion, or a
       script error all land in the same place: the page as served.
   ========================================================================== */
