+// Driving adapter: gRPC API (skeleton machinery, transport-only).
+//
+// A SmartLifecycle bean (GrpcServerRunner) owns the io.grpc Netty server, so this module depends on
+// NO third-party grpc-spring-boot starter (no Spring Boot version coupling). The skeleton compiles
+// NO protobuf: there is no `com.google.protobuf` plugin and no `.proto` here — health + reflection
+// come from grpc-services at runtime, and feature `.proto`/services live in the sample module.
+//
+// io.grpc:* / protobuf versions are NOT managed by the Spring Boot BOM, and this repo has no version
+// catalog, so the grpc-bom + protobuf-bom platforms are imported HERE (module scope) using the root
+// `ext.grpcVersion` / `ext.protobufVersion` SSOT — this keeps the strict-locking blast radius to
+// this module (the shared root dependencyManagement block stays io.grpc-free).
