   SKINRUSH — PREMIUM POLISH LAYER
   Loaded LAST (after styles.css + ssr.css). Purely additive:
   refines depth, light, motion and touch. No layout is moved,
   nothing here changes element box sizes on desktop — every
   rule adds shadow / sheen / easing / focus, so it can be
   removed with zero regressions. Reuses existing :root tokens.
