+ * Marker interface for all domain (and plugin) service classes.
+ *
+ * It carries no required methods on purpose. Real services have wildly different shapes
+ * (the Tickets service alone has ~75 heterogeneous methods), so a fixed CRUD contract
+ * never fit — which is exactly why the previous patch/update/create/delete/get/query
+ * interface had zero implementers. This marker instead gives the service layer a single
+ * type to scan for and a shared home (via {@see BaseService}) for the cross-cutting
+ * authorize()/validate() helpers, without forcing a fictional method surface.
+ *
+ * Granular capability interfaces (e.g. a real Crudable) may be introduced alongside this
+ * marker where they genuinely apply, opt-in per service.
