			==== Client-side TLS 1.3 and post-handshake authentication ====

			Janus client connections (for example, <var class="term">$SOCK</var>-based clients
			and Janus Web Server outbound HTTPS requests) now negotiate and complete a full
			TLS 1.3 handshake as the client, including X25519 key exchange, the HKDF-based
			key schedule, and RSA-PSS certificate verification of the server.

			Client certificate authentication is supported both during the initial handshake
			and after it completes. When a TLS 1.3 server sends a post-handshake
			<code>CertificateRequest</code> (RFC 8446 Section 4.6.2) — for example, when a
			server application requests a client certificate on a connection that did not
			originally require one — the Janus client automatically responds with its
			<code>Certificate</code>, <code>CertificateVerify</code>, and <code>Finished</code>
			messages, allowing the authenticated request to proceed without interrupting the
			connection.

			No application changes are required. Post-handshake authentication is used
			automatically when a server requests it and a client certificate is available for
			the port.
