/* Palette sampled directly from the official Wildwood trail map PDF.
   Every ratio below was measured against the *lightest* backdrop each colour
   can actually land on — the horizon glow flattened with the 5–13% overlays
   used by cards, panels and chips — not just against flat --forest. That is
   why jade is split in two: the map's jade only reaches 3.7:1 and cannot
   legally carry small text.
     --jade       decorative fills only          (worst 3.0 — never text)
     --jade-text  all small jade text            (worst 4.96, need 4.5)
     --line       borders and control boundaries (worst 3.30, need 3.0)
     --mint-dim   secondary text                 (worst 5.77)
     --gold       error text                     (worst 4.87) */
