The three effects had drifted apart from each other and from the token system. Consolidate them behind --crt-* tokens and fix what was broken. - The animated text-shadow silently overrode the static one, so reduce-motion users saw a 5px white glow and everyone else a 3px currentColor glow. Both now come from one declaration, with the aberration offset factored out into --crt-shift. - Step the aberration instead of tweening it. text-shadow is not compositable and this one inherits to every glyph, so the smooth version repainted the whole document at refresh rate. - The flicker was invisible: a near-black tint at an effective alpha of 0.008-0.096 over a black background, a peak lift of under 2/255. Retint with the accent at ~3%. - Anchor the vignette to the viewport. It was sized to body's box, which is document-height, so on long pages the bloom sat off-screen. - Pin the overlays with position: fixed rather than painting document-sized layers, and give the grille hard stops so it is three stripes rather than a smooth R->G->B ramp. - Scale the raster pitch down at >=2dppx, where a 2px scanline is 4 device px and resamples into moire at fractional DPR. - Raise --color-mg to oklch(0.62): at 0.5 it was 3.5:1 on the background and 1.7:1 over the vignette centre. Halve the vignette alpha via its own token, keeping --color-accent-transparent at 50% for ProjectCard's glow. Collapses the two keyframe blocks from 193 lines to 40.
