This endpoint negotiates the TLS 1.3 key-exchange group
X25519MLKEM768, a hybrid of classical X25519 and the standardised
ML-KEM-768 (Kyber). It is quantum-safe against the
harvest-now-decrypt-later threat to the key exchange.
X25519MLKEM768. The certificate signature
stays classical, because public CAs do not issue PQC certificates yet. That is
the expected state of hybrid PQC TLS today.
