Grain

Film-grain noise overlay for the whole page or a single element, built from one cached SVG tile, with optional jitter and any blend mode.

Scope grain to one cover with position="absolute". An overlay blend keeps the noise in the mid-tones, like film.

Film grain lives between 0.04 and 0.12 opacity; push past 0.2 only for deliberately gritty, poster-like surfaces. Same artwork, four strengths.
