/* ============================================================================
   STYLE MAP
   Keep this file in runtime order. The entry screen, hero water surface,
   services scroll story, and work gallery rely on later override layers.

   Safe edit zones:
   1. tokens and base page styles
   2. top/bottom navigation
   3. content sections: about, services, works, contact
   4. final correction layers at the end of the file

   Frozen visual chains:
   - entry packaging seal and calibration styles
   - hero kinetic water canvas and hero scroll progress
   - services white-stage transition
   - work gallery overlay and horizontal/detail motion
