 * LibreLink Up (FreeStyle Libre — the OTC sensor) community-proxy endpoints.
 * The LibreLink Up companion API is what the official "follower" app talks to;
 * it is the only practical way to read Libre 2/3 data without a hardware NFC scan.
 *
 * Regional bases: Abbott shards LibreLink Up by region. `LIBRELINKUP_REGION`
 * (e.g. "eu", "us", "de", "fr", "au", "jp") selects the shard. Default "eu"
 * (api.libreview.io). After login the response can ask the client to redirect
 * to a region-specific host (`data.redirect` / `data.region`); the client
 * follows that automatically.
