JSON Schema of the .ufp part spec

The typed vocabulary of a .ufp manifest's spec (material, color, finish, quantities, thickness_in, tapping, inserts, bends, cut, size_in), generated from the protocol's zod schemas. Its record rows are the exact shapes POST /v1/quotes/{id}/refine validates, so a client that conforms never sends a record the network rejects. The manifest schema is served beside it at /v1/ufp/ufp.schema.json. Public, no key.
