+| `tube.jihakuz.xyz` | nginx → `127.0.0.1:8086`, ytstream's admin UI |

+| Cron | `ytstream run` hourly, `update-ytdlp.sh` Mondays, inherited UUIDs |

+The 108 queued channels were approved rather than curated, because the brother's
+subscription list is defined as the source of truth (§4): hand-picking a subset means
+he subscribes to something and nothing happens, which is the feature not working.
+Reversible per channel with `ytstream unsubscribe`.
