+Classroom API - Legacy Import Wrapper
+
+This file provides backward compatibility for code that imports from classroom_api.
+All functionality has been moved to the classroom/ module.
+
+Usage (new):
+    from classroom import router as classroom_router
+
+Usage (legacy, still works):
+    from classroom_api import router
