DESIGN.md (and .impeccable/design.json) replace the June v3 spec with the
shipped Night Arcade system, derived from tokens.css and core.css: the
stage, ink tiles, white cards, keys on a lip, colour rationing, the board
palettes, Rubik with the pinned display face, motion and feel, RTL, and
the theming contract.

The documenter's audit found the code breaking its own rules: a white rim
on top of every key and the play key read as gloss (removed), the green
and orange faces had a lighter top that dropped white text under 3:1
(both are one flat colour now, orange deepened to 3.4:1), and small green
keys carried 13-14px text at 3.1:1 (they use a deeper green, 5:1). The
CTA glint stays, recorded as motion.
