Two themes replace the navy GameCult theme. Every colour is a bark, leaf, soil
or pigment albedo times the irradiance sun.js gives for a fixed moment (equinox
noon and midnight, 45N). scripts/bake-sky.mjs writes src/sky/baked.ts: the
terrain-free sky gradient used as the fallback background, folds tokens for
panels and buttons, chat bubble colours, link and name colours.
skyTokens.test.ts holds every text pairing to WCAG AA and fails if baked.ts is
stale.
