   Palette from research/design-language.md. Dark is the default theme.
   Token roles are deliberately separated (see design-language warning):
     --on-brand      = text/icons sitting on a saturated brand-colour fill
                       (hero, buttons, footer). Stays light in BOTH themes.
     --text / --surface = page copy + card fills. These flip per theme.
