  /* Palette pulled from the OPT Bird Tribe shirt — a sun-bleached
     desert-day version of the split-complementary : warm cream
     anchor, dark warm text, with the same coral + yellow + sky-blue
     + magenta triad as accents. The shirt's body is sky-blue ; its
     circle is dark ; its textile pulls hot accents. We invert into
     a light register that reads in daylight.

     Color-science layout (60-30-10) :
       60%  warm cream anchor (bg, bg-alt, bg-card, bg-deep)
       30%  warm dark text (ink) + warm grey (muted)
       10%  triadic accents :
              coral       (primary CTA, links)
              yellow      (secondary accent)
              sky-blue    (deeper variant for legibility on cream)
              magenta     (sparingly)

     Dark-on-bg contrast ≈ 14:1 ; coral-on-bg ≈ 4.6:1 — WCAG AA.
     For coral buttons we keep dark text on coral (≈ 5.5:1 contrast). */
