/**
 * The address a phone on the same network can reach this machine at.

 * `bitmagic dev --mobile` has to put a URL on screen that a creator scans and their phone resolves,
 * and the only thing that can answer "which of my addresses is that" is the host's own interface
 * list. There is no discovery here and no mDNS: a `.local` name works on Apple devices and fails
 * quietly on many Android ones, whereas a literal IPv4 works everywhere and is what the certificate
 * has to name anyway (`dev-cert.ts` puts it in the SAN).
 *
 * Only PRIVATE IPv4 addresses are offered. A machine with a public address on an interface would
 * still bind it — the bridge listens on 0.0.0.0 — but printing it, and drawing a QR of it, would
 * invite a creator to hand out a URL that is not merely LAN-visible. Loopback is excluded for the
 * obvious reason, and 169.254/16 because an interface that self-assigned has no network to be on.
