- VisualEffects.destroy() puts skyBox.milkyWayVisibility back to 1, as it already restores the borrowed bloom stage, so a surviving viewer does not keep a faded sky. - Rename scripts/qa-anime-space-mask.mjs to qa-anime-sky.mjs: rewrite the header for the current approach, drop --space-expr and --repo, import puppeteer as a package, reject unknown cases and count the milkyway case as reached only while the anime stage is on. - Put both sky QA scripts under format:check.

/**
|
|
* qa-anime-sky — the anime style must cel-shade the Earth, and leave the sky
|
|
* without bands.
|
|
*
|
|
* Earlier the anime shader exempted the far plane, judged from the
|
|
* post-process depth, from its luminance bands. That depth cannot tell the
|
|
* sky from far geometry, so the Earth lost its bands. The shader now matches
|
|
* main, and src/ui/visualEffects.js fades the Milky Way out with the style.
|
|
* Each case runs headless against a Vite dev server:
|
|
*
|
|
* satellites whole globe from 20 000 km with the satellites layer on
|
|
* (near clamps to 0.1 m): no Earth pixel may skip the bands.
|
|
* keyless keyless stack, Denver 1700 m looking west: no terrain pixel
|
|
* above the ellipsoid horizon may skip the bands.
|
|
* milkyway the real anime style, looking away from the Earth at the
|
|
* Galactic Centre: at most 0.5 % of the sky (the stars) may
|
|
* reach the first band.
|
|
*
|
|
* The first two cases compile the checkout's anime shader with a debug
|
|
* output (R = pixel skipped the bands, G = raw depth 1.0) as an extra stage.
|
|
*
|
|
* Usage: node scripts/qa-anime-sky.mjs [--url http://localhost:4333/] [--case satellites|keyless|milkyway|all]
|
|
* Exit: 0 all pass, 1 a case failed, 2 a scenario was not reached or the case is unknown.
