/* Gradient dither — break up Firefox/WebKit color banding on the page
   background. Chromium dithers CSS gradients; Firefox/Safari don't, so the
   135deg linear gradient above shows visible stair-step bands on those
   engines (caught by the platform glow-banding e2e). A near-invisible
   (3.5% opacity) fractal-noise overlay scatters the quantization so the
   transition reads smooth. Fixed + pointer-events:none + z-index:-1 keeps
   it behind all content (the white cards sit on top); only the exposed
   gradient margins carry the dither. Same technique as the platform theme. */
