/* High contrast mode.
   Every component below reads its colors from the tokens (--ink,

   just body's background/color, means every current AND future
   component is covered automatically, including ones built on a tint
   token rather than a hardcoded color. This must come after the dark
   mode token blocks above so it always wins when both are active —
   high contrast should never leave near-white text on a near-white
   forced background (or vice versa) just because dark mode also has
   an opinion about what --ink means. The specific overrides below are
   kept as an extra safety net on top of this, not a replacement for it. */
