- Override Tailwind ease-out/ease-in-out with stronger curves, add ease-drawer - hoverOnlyWhenSupported so hover styles never stick on touch devices - Replace transition-all with explicit properties across the public UI - Press feedback via active:scale-[0.97] instead of hover:scale-105 - Global prefers-reduced-motion handling (CSS + MotionConfig reducedMotion="user") - Mobile menu is a real drawer: stays mounted, inert when closed, Escape closes - Progress and music bars animate scaleX/scaleY instead of width/height - Fix undefined animate-spin-slow, contain hero CTA shine with overflow-hidden Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
