Promote the static /learn guide catalog into a typed concept-to-slug lookup the deterministic UI surfaces can consume. learnUrl is the only sanctioned /learn URL builder and learnLinkForMetric fails closed for an unmapped id. A test asserts every mapped slug resolves in the catalog, so the mapping can never point at a guide that does not exist.
