+// Integration test: creator list response with partial database results
+//
+// Verifies that when the database returns fewer items than the requested page size
+// (simulating a partial result set), the response is still valid and the
+// pagination metadata accurately reflects the total count and the partial items.
+//
+// Scope: exercises the complete response envelope and pagination metadata shape
+// when fewer results than the limit are returned due to a database limitation
+// or partial failure.
