*
* NIST SP 800-38D requires a different counter-derivation path when
* len(IV) != 96 bits (12 bytes): J0 = GHASH_H(IV || pad || len64(IV)).
* Most hardware accelerators only support the 12-byte fast path, so these
* tests are skipped on FIPS builds and hardware-only backends.
*
* Three sections:
* 1. 1-byte IV - FIPS CAVS example vector (AES-128).
* 2. 60-byte IV - McGrew & Viega Test Case 12 (AES-192).
* 3. Variable IV length loop (1..GCM_NONCE_MAX_SZ, AES-128): roundtrip and
* uniqueness - each distinct IV length must produce distinct ciphertext.
* 4. Zero-length IV must be rejected with an error.
