/* Film grain — a fine noise tiled over the hero only (borrowed from
   latitude.so). The grain is baked into the SVG's *alpha* (white speckles on a
   transparent ground) and composited with normal blend, so it renders evenly
   over the dark base AND the colored hero gradient — unlike an overlay blend,
   which cancels out over mid-tones. It's an absolute layer scoped to the hero
   region at z-index:0, so it sits above the gradient/grid but below the hero
   copy and the product screenshot (both z-index:1), and never reaches the
   sections below. The bottom edge is masked so it fades out, not hard-cuts. */
