   WORLD TAEKWONDO MANDEVILLE — DESIGN SYSTEM v4
   Structure: the examination ledger / dojang manual (hairline
   rules, sharp corners, serif headings, no AI-gradient tells).
   Palette: the crest's DOMINANT colors — the blue-headgear
   fighter, the red-headgear fighter, and "MANDEVILLE" green —
   are the primary, visible scheme. Orange ("WORLD") and gold
   (Korean lettering) are minor trim only, never primary accents.
