The dark and light covers move up beside the generator as the shipped assets;
the six exploratory variants and the contact sheet go.
Trims the generator to match: VARIANTS is now only the two covers, and with the
retired variants gone so are the knobs nothing reaches any more — the wordmark
caption, the branded palette, the whole-board height fit and the non-brand tile
face. Left behind, they would read as supported options that no output exercises.
`node build-cover.mjs` now reproduces exactly the two committed PNGs.
