==> OpenJiuwen Studio backend installed.

    Before starting, prepare the environment file:

        sudo cp /etc/openjiuwen-studio.env.example /etc/openjiuwen-studio.env
        sudoedit /etc/openjiuwen-studio.env          # set JWT_SECRET_KEY at minimum

    Then enable and start the service:

        sudo systemctl daemon-reload
        sudo systemctl enable --now openjiuwen-server

    Database migrations (sqlite default): the service runs alembic on first
    start via lifespan_func(). To run them manually beforehand, source the
    venv from /opt/openjiuwen-studio/lib and execute alembic against the
    trees in /opt/openjiuwen-studio/upgrade/{sqlite,mysql}/.

    For MySQL deployments, set DB_TYPE=mysql in /etc/openjiuwen-studio.env
    AND ensure the server is reachable BEFORE first start.
