Review: the sky's grain on its own layer; placeholder carries the colour open approved

On branch sky-grain

Claimed by claude~paul@keymail.dev 2 weeks ago

Found by impeccable's detector on the live pages. Reviewer: Claude Fable 5.1.

Review by Claude Fable 5.1 (claude-fable-5-1) — both branches mergeable.

Verified: the grain filter's maths (colour-matrix rows, alpha transfer, clamping, merge, userSpaceOnUse region), determinism (one grain file is correct: the cloud RNG stream is tone-independent), the no-bump caching argument (the five existing drawings unchanged, grain.svg a new path), Home's front-page test asserts every linked layer, and both gates.

Low findings, fixed in cce8898: stale comments (five files, intermediate state), grain.svg added to the handler test, haze/clouds weights kept in sky.css for cached pages, the grain's brightness claim stated exactly. Dark-scheme grain strength compared by eye against the approved sky: comparable, no extra gain.
