+
+// The server file starts an HTTP server on import, so we intercept
+// the listen call and extract TeamRoom via a small trick:
+// we require the file, then grab the class from the module's scope.
+// Since that's not straightforward, we re-define TeamRoom here
+// mirroring the production code, or better: we spawn a child process
+// that loads the server and runs our test logic.
+
+// Simpler approach: directly require the server and capture the class.
+// The server calls server.listen() but we can override before that.
+
+// Best approach for unit testing: extract TeamRoom into its own module.
+// For now, we duplicate the class definition for isolated unit tests
+// and also do an integration test that actually starts the server.
