  Discova shared site styles.
  Color tokens are drawn from src/constants/theme.ts (light = lightColors,
  dark = darkColors). Purple is the lead brand color in both modes on the
  website; blue is used as a supporting accent (it's the app's own dark-mode
  primary and shows up as the secondary "food" hue in light mode), so both
  are present but purple stays dominant throughout.
