Three pieces so kadence.timka.su can be stood up and updated from the repo
rather than from shell history on the box:
* `docker-compose.prod.yml` — publishes the app on loopback only. The base
file's `${APP_PORT}:8000` binds every interface, which on this host both
collides with remnawave (already on 8000) and would serve the API beside
the proxy without TLS. Compose *appends* merged port lists, so the override
needs the `!override` tag or the public binding survives. uvicorn also gets
`--proxy-headers`, without which every request looks like plain HTTP from
127.0.0.1 and the session cookie loses its `Secure` flag.
* `deploy/nginx/kadence.timka.su.conf` — TLS, HSTS, the forwarded headers the
cookie logic reads, and a 120s read timeout because one task refresh fans
out to four third-party APIs.
* `deploy/deploy.sh` — idempotent install-or-update. Generates API_TOKEN and
the database password once and never rotates them afterwards (that would
lock out the phone and the desktop app), treats `.env.example`'s
`change-me` placeholders as unset, and uses `certbot certonly --webroot`
rather than `--nginx` so the vhost in git stays the truth.
