/* ==========================================================================
   PCPMotion — shared animation primitives
   --------------------------------------------------------------------------
   CSS support for assets/js/motion-engine.js. These classes are not applied
   to any page yet — they exist so a future section can opt in by adding the
   class name, without inventing new CSS each time. Colors/easing reuse the
   tokens already defined in assets/css/site.css (:root), so there is one
   source of truth for brand values.

   Every rule here animates only `transform` and `opacity` (per project
   guardrails) and every effect has a `prefers-reduced-motion` fallback.
