/* ============================================================
   THEME: mocha-truffle-warm
   Mocha Truffle Warm — rich espresso-brown surface + caramel
   Mood: dark-warm-mocha-cozy-premium
   Path B theme (recipe palette). Riding Mocha Mousse (#A47864, a
   recent Pantone Colour of the Year) — "a rich, earthy brown,
   quiet sophistication, an unpretentious classic." The set had NO
   brown-background theme (dark-warm-brass is near-black + gold;
   warm-clay-earth is a LIGHT terracotta). Deep truffle base, lifted
   brown sections/cards (cards ABOVE section), caramel accent,
   Fraunces serif. Reads coffee / chocolate / bakery / leather /
   fashion / interiors / artisan-premium. All AA-checked.
   Added 2026-06-09 (user request: +4 trend themes, 18 -> 22).
