 * 2. a full JSON fixture (`{ username, password }`);
 * 3. a **name-only** fixture (`{ username }`), whose password is resolved at
 *    `login()` time by {@link resolveE2EPassword} — env-first (`E2E_PW_<SLUG>`,
 *    set by the CircleCI context in CI) then Vault locally. No `globalSetup` is

 *
 * Throws if none yield a complete pair. Async because the name-only path (step 3)
 * may reach out to Vault.
