/**
 * Strict Zod schema for the OB 3.0 EndorsementCredential envelope (§B.1.7) and

 *
 * **envelope recognition only**. No semantic checks for endorsement content, no
 * auto-walk of `issuer.endorsement[]` / `achievement.endorsement[]` /
 * `credentialSubject.endorsement[]`, no recursive verification. Consumers who
 * want endorsement verification today extract embedded endorsements themselves
 * and call `verifier.verifyCredential(endorsement)` — recognition surfaces the
 * typed normalized form on the result so they can branch on `recognizedProfile
 * === 'obv3p0.endorsement'`.
 *
 * Reuses inner-class schemas (`Obv3p0Image`, `ProfileRefField`,
 * `JsonLdTypeField`) and shared envelope helpers (`Obv3p0ContextArray`,
 * `zodErrorToProblems`).
