    # File ownership inside the data and logs volumes is normalised by the
    # entrypoint at startup (chowns to PUID:PGID and drops privileges via
    # gosu before running the app). Override PUID / PGID below to match
    # your host user if needed — defaults to 1000:1000 to match the
    # historical compose `user:` directive.
    #
    # Allow binding to privileged ports (322, 990) as non-root user — required
    # for FTPS in every VP mode and for the RTSPS camera proxy in proxy mode +
    # non-proxy modes that have a target printer configured. Without this, the
    # FTP and RTSP listeners silently fail.

      # OPTIONAL — only needed if you ALSO run a native install of Bambuddy
      # on the same host and want both installs to share the same Virtual
      # Printer CA certificate (so the slicer only has to trust one CA).
      # Most Docker-only users should leave this commented out — the
      # entrypoint will keep the VP data inside the named volume above.
      # If uncommented, the entrypoint chowns the host directory to
      # PUID:PGID on first start so the container user can write to it.

      # Mount scheduled backup output to NAS or external storage

      # Tailscale integration (optional): mount the host's tailscaled socket
      # so Bambuddy can request Let's Encrypt certs for virtual printers via
      # your tailnet's MagicDNS name. Requires:
      #   1. Tailscale installed + `tailscale up` completed on the host
      #   2. `sudo tailscale set --operator=<container-user>` on the host so
      #      the user running the container can call `tailscale cert`
      # Without this mount, the Tailscale toggle in the UI is harmless —
      # Bambuddy falls back to self-signed certs.

      #
      # Using a self signed certificate for Home Assistant
      # Add your certificate to certs directory and mount it to the container.
      # The certificate will be added to the system trust store on container startup.

      # have Bambuddy trust the certificate.
