/* ============================================================
   PRODUCTS-FILTER.CSS  (v5.7.20)
   Category filter for products.html — loader + choreographed motion.

   Rules of the road
   - Only transform / opacity / clip-path-free properties are animated.
   - Entrance uses the *individual* transform properties (translate / scale)
     so it never fights hover transforms or the floating icons' keyframes.
   - Everything is gated by .pf-on (added by JS). No JS = full page, untouched.
   - prefers-reduced-motion = instant swap, no skeleton, no loader.
   ============================================================ */
