/* Treasure Hunt 2026 — palette taken from Monica's campaign artwork: CBL teal
   deepening to night at the top, with the brand lime as the accent throughout,
   paper-white cards, and a typewriter slab for anything that belongs to the hunt
   itself.

   Lime clears WCAG AA on the dark teals (6.7:1 on --teal-night, 5.5:1 on
   --teal-deep). --lime-ink is the darker mix for anything sitting on paper. */
