Overview

A class-keyed lookup with ancestor fallback, in registration order. Consumers register their own model classes to payloads (lambdas, strings, prefixes); the table — and therefore this gem — carries no model knowledge. The metanorma-document and metanorma-standoc seeds register their classes at load time.
