+// This Protocol Buffers file defines the gRPC contract for the PostService.
+// It includes service definitions for creating, retrieving, updating, deleting,
+// and listing posts. Each RPC method has corresponding request and response
+// messages. The syntax follows proto3 conventions and uses message types for
+// structured data exchange between microservices.
+//
+// Syntax:
+// - Uses proto3 syntax for modern Protocol Buffers features.
+// - Defines service and message types for CRUD operations.
+// - Supports repeated fields for listing multiple posts.
+//
+// Purpose:
+// - Enables strongly-typed, language-agnostic communication between services.
+// - Provides a contract for backend and API Gateway integration.
+// - Facilitates code generation for gRPC servers and clients.

+//
+// This Protocol Buffers file defines the gRPC contract for the PostService.
+// It includes service definitions for creating, retrieving, updating, deleting,
+// and listing posts. Each RPC method has corresponding request and response
+// messages. The syntax follows proto3 conventions and uses message types for
+// structured data exchange between microservices.
+//
+// Syntax:
+// - Uses proto3 syntax for modern Protocol Buffers features.
+// - Defines service and message types for CRUD operations.
+// - Supports repeated fields for listing multiple posts.
+//
+// Purpose:
+// - Enables strongly-typed, language-agnostic communication between services.
+// - Provides a contract for backend and API Gateway integration.
+// - Facilitates code generation for gRPC servers and clients.
+// -----------------------------------------------------------------------------

+// This Protocol Buffers file defines the gRPC contract for the UserService.
+// It includes service definitions for creating, retrieving, updating, deleting,
+// and listing users. Each RPC method has corresponding request and response
+// messages. The syntax follows proto3 conventions and uses message types for
+// structured data exchange between microservices.
+//
+// Syntax:
+// - Uses proto3 syntax for modern Protocol Buffers features.
+// - Defines service and message types for CRUD operations.
+// - Supports repeated fields for listing multiple users.
+//
+// Purpose:
+// - Enables strongly-typed, language-agnostic communication between services.
+// - Provides a contract for backend and API Gateway integration.
+// - Facilitates code generation for gRPC servers and clients.

+// This Protocol Buffers file defines the gRPC contract for the UserService.
+// It includes service definitions for creating, retrieving, updating, deleting,
+// and listing users. Each RPC method has corresponding request and response
+// messages. The syntax follows proto3 conventions and uses message types for
+// structured data exchange between microservices.
+//
+// Syntax:
+// - Uses proto3 syntax for modern Protocol Buffers features.
+// - Defines service and message types for CRUD operations.
+// - Supports repeated fields for listing multiple users.
+//
+// Purpose:
+// - Enables strongly-typed, language-agnostic communication between services.
+// - Provides a contract for backend and API Gateway integration.
+// - Facilitates code generation for gRPC servers and clients.
+// -----------------------------------------------------------------------------
