   KOI — Knowing Others to Inspire
   Design system: "school of koi" — a warm pond palette where each program /
   section gets its own hue from a neurodiversity-spectrum accent set. The
   signature is the drifting koi-wave divider and the spectrum underline.
   Display: Fraunces (soft, characterful). Body: Mulish (warm humanist sans).
