   MOBILE TAP RELIABILITY
   Fixes the "sometimes my tap works, sometimes it doesn't" problem:
   - touch-action: manipulation removes the 300ms delay + double-tap-zoom
     interception that swallows quick taps.
   - decorative pulse rings / icons never intercept the touch.
   - on touch devices, controls don't lift/scale on "hover" (which moves
     them out from under your finger and eats the first tap).
