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.
