The QR mirrored the browser origin — an operator browsing over Tailscale
handed the phone a 100.x address it has no route to, so pairing silently
never connected (reported 2026-07-22; the 'random password' alongside it
was the device token working as designed). system.get-hostname now also
returns the default-route LAN IPv4; the QR substitutes it (or the mDNS
name) whenever the origin is localhost or a CGNAT/tailnet 100.64/10 IP.
