  The module does not implement the `Lamina` behaviour.

  During startup, the Lamina server double checks that the module it's been
  asked to manage actually is a Lamina module and not just some other random
  module.  Really the only way you should ever see this error in the wild is if
  you try and manually start `Lamina.Server` - which you probably shouldn't be
  doing anyway.
