/* Brand palette approximates Cash Converters' own red/yellow/charcoal
   identity (see README.md). Light by default, with a dark variant that
   follows the device's light/dark setting (prefers-color-scheme) - there's
   no in-page toggle. The brand red header and yellow accents stay the same
   in both; dark mode only swaps the neutrals and lightens the red where
   it's used as text on a dark background (--blue, --link). --good/--critical
   stay semantic (price down/up), independent of the brand accents. */
