AppBuildInfo gains releaseServerUrl, which :app fills from RELEASE_SERVER_URL (https://<kvitt.publicHost>:8443, D-121). AboutRepositoryImpl shows it while no server is paired, in place of DataModule.DEFAULT_SERVER_URL, which is deleted: :data no longer names a host. The fakes' AboutState uses the fixture https://kvitt.example.org:8443; 30 S-21/S-22 goldens re-recorded (only the host changed; oxipng -o 4 --strip safe). New test: unpaired About shows the release server. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01TQd3pEP9UeN2uifbHknQ7B
