/* Light-mode chip/badge/tag/state contrast.
   The status colours throughout the app are bright pastels tuned for a dark
   translucent chip; on the near-white light card the same text on a faint tint
   falls below WCAG. Override every tinted-background label to a deeper 700-level
   shade of the same hue (grouped by colour). Plain links / menu items / borders
   are intentionally excluded - those are a separate concern, not tinted chips.
