 ### Rule
 
-Make each guest module a wrapper around its service module.
-Enable the service module through `guests.<name>.interior`.
-Keep service configuration in `modules.services.<name>`.
-Use the guest module to pass paths and secret files to the service module.
-Use the guest module to configure bind mounts, resource limits, and registry entries.
-Keep guest modules independent of hosts.
-Put host paths, served volumes, guest addresses, and routes in host configuration.
