// minimal_https.cpp - enable HTTPS via the use_ssl / https_mem_key /
// https_mem_cert chain on create_webserver.
//
// The https_priorities call sets an explicit GnuTLS cipher-priority string
// that allows TLS 1.2 and TLS 1.3 with safe renegotiation. Without it,
// GnuTLS may fall back to TLS 1.0/1.1 depending on the system configuration.
// Port 8443 is used (convention for HTTPS on non-privileged ports).
