feat: polish motion with stronger easing, press feedback and reduced motion (#73)

- 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
