Token hygiene check

Every colour in this product comes from shared/tokens/brand.css. A colour written directly into a component breaks that: the day the brand colour changes, it silently will not move with everything else.

Clean. 7 styling files scanned, no colour written outside the token layer.

Scanned: 7 files. Exempt (these are the token layer): shared/tokens/brand.css, shared/tokens/theme-light.css, shared/tokens/_derived.css.
