Different bright spots should slowly fade in and out." - NO movement anywhere in the background: no grid drift, no transform/scale, no background-position animation. The 44px/60s grid drift (0.73px/s, diagonally down-right) rasterizes sub-pixel by sub-pixel and reads as a once-per-second jitter; the 14s whole-layer opacity+scale pulse reads as a uniform blink. Both are gone. - Three independent soft glow spots, each fading in and out on its own SLOW opacity-only cycle — 26s / 34s / 42s, ease-in-out, with negative delays (-12s, -23s) so the cycles run out of phase (LCM 4641s: the composite pattern effectively never repeats within a viewing session). The total light fluxuates smoothly and irregularly. - html::before / html::after join body::before / body::after as background layers: is the root stacking context, so their z-index:-1 pseudo-elements paint ABOVE the var(--bg) canvas and BELOW the transparent, non-stacking 's content — the no-occlusion contract (html owns the canvas, body stays transparent) is unchanged. - No filter (phase-08 no-blur perf anchor), no JS, no new assets; opacity-only keyframes stay compositor-friendly. - prefers-reduced-motion: reduce stills all four layers. */ /* Static grid texture: 44px cells, 1px lines at 60% --line alpha, masked with a widened radial fade (visible across most of the viewport, fading to the corners).
