// Firmware before the Dutch-MeshCore merge 32dd8ad (2026-10-19) does not parse a
// scheme in mqtt1.server and builds "<proto>://<host>:<port>" with proto taken
// from the port alone (8883 mqtts, 443 wss, else mqtt). A bare host works on
// both; the scheme is only written when the port would infer the wrong one.
