   MOBILE OPTIMIZATION — performance-first glass + touch-native motion (≤760px)
   The phone experience was "much worse" for two reasons screenshots can't show:
   (1) backdrop-filter:blur(48px) re-samples the backdrop EVERY scroll frame on
       20-34 glass cards per page → severe scroll jank on real phones; and
   (2) the rich desktop motion (hover sheen, card lift) is pointer-only, so touch
       got a flat, lifeless surface.
   Fixes: the blur radius is the dominant GPU cost, so it's cut hard — the frosted
   look is carried by the gradient fill + bright top edge, which stay; touch gets
   its own press + reveal-shimmer vocabulary. `html:root` (0,1,1) placed AFTER the
