/* ========================================
   MOTION LAYER
   Shared keyframes, shimmer loaders, illustrated empty states, and a
   subtle shine animation for the badges-page progress bars. Honors
   prefers-reduced-motion.

   The XP chip / streak flame / daily challenge / celebration overlay /
   confetti / XP float blocks were removed after user feedback on the
   gamification layer — kept minimal animation primitives only.
