/**
 * Marks this package as the root of the domain layer.

 * The domain layer must not depend on any infrastructure, application or
 * presentation/UI code, and in particular not on persistence (Persistence
 * Ignorance). To this end, the domain layer typically declares Service and
 * Repository interfaces that are implemented technically in the infrastructure
 * layer.
