+### User Story
+
+As a pet clinic administrator, I want to add a `/greetings` API endpoint that returns a personalized welcome message so that I can display it on the homepage.
+
+Acceptance Criteria:
+- Endpoint: `/api/greetings`
+- Method: GET
+- Optional query param: `name`
+- Returns: "Welcome to the PetClinic, <name>!" or "Welcome to the PetClinic!" if no name is passed.
