 * Duneed — the one stylesheet for apps/web (ADR 049).

 * Colours are the app's own tokens (apps/mobile/src/core/ui/tokens.ts), so the
 * site and the product do not drift into two different greens. Light is the
 * base and dark is a media-query override, exactly as the app resolves its
 * palette from the system scheme.
