## What's inside.

## All systems —
one library.

Every system ships a deterministic OKLch palette, a font stack, and a tone profile. Pick one tile and the agent inherits the whole brand.

S eventy-one product systems, two hand-authored starters, five visual directions. Imported and curated from awesome-design-md, hand-tuned for Open Design's discovery loop. Drop one in, every artifact downstream changes accordingly — no model freestyle.
