 Set `PUBLIC_BASE_URL=https://<DOMAIN>` in beaver-agent's `.env`. For per-subdomain layout, rewrite the Caddyfile and pass full `public_base_url=...` per frontend in `config.py`.

+`uv sync --extra prod` pulls the gateway from git instead. Neither is used
+by the image - the container builds the gateway itself.
