/* === GRAIN: softer + cheaper on mobile ===
   mix-blend-mode forces a full-viewport re-composite on every paint. Combined
   with a transform-animating card image on hover, that causes severe jank
   ("freeze") on mobile GPUs and in narrow desktop windows. Drop the blend on
   small screens — a plain low-opacity noise reads the same but costs nothing. */
