   Palette is authoritative: Charcoal #1F1F1F · Bronze #B08D6B ·
   Soft White #F9F7F4 · Warm Gray #A7A29A · Olive #3C4A3F
   Espresso #3B2F28 · Sand #DCCDBF · Sage #7F8C7A · Stone #EAE6E1

   Contrast rules baked into the tokens:
   - Bronze #B08D6B on Soft White = 2.86:1 — never used for text on light.
   - Warm Gray #A7A29A on Soft White = 2.37:1 — never used for text on light.
   - Bronze Deep #8A6A4A = 4.63:1 on Soft White  -> bronze text on light.
   - Warm Gray 700 #6E6A63 = 5.03:1 on Soft White -> muted text on light.
   - On Charcoal: Bronze 5.39 · Warm Gray 6.50 · Sand 10.62 — all fine.
