/* GTO Admin UI design system — docs/specs/admin-ui-redesign.md.
   Colours are light-dark() tokens. Text takes contrast-color() of the
   surface it sits on; the declaration before it is the fallback for
   browsers without contrast-color(). No colour here may drop text below
   the contrast rule: browser E2E every_text_meets_contrast_in_both_themes. */
