A multi-homed machine (VM bridges, Ethernet + Wi-Fi) has several
addresses and the server cannot know which network the phone is on —
but the OS's default route is the right answer nearly always. The
banner now prints one "on your phone" URL from the route probe, with
the other interfaces on an if-that-doesn't-answer line; when the probe
fails, the settings hint plus candidates.
