+//
+// These views instantiate their controllers internally (e.g.
+// `late final _controller = HomeController();`) rather than accepting them
+// via constructor injection. Their controllers in turn call the global
+// service singletons (HouseService.instance, NoteService.instance,
+// PhotoService.instance, ChecklistService.instance) which perform real HTTP
+// calls via ApiClient.instance (no mock HTTP client hook). Rendering any of
+// these views in a test causes them to start a real network request and
+// either hang, throw, or log noisy async errors.
+//
+// To enable smoke tests here, the production views would need one of:
+//   1. An optional `controller` constructor parameter that defaults to a new
+//      one, so tests can pass a fake.
+//   2. A dependency-injection point for the backing services (e.g. a
+//      `ServiceLocator` or a constructor parameter).
+//   3. An HTTP client override on ApiClient so tests can replace it with a
+//      fake that returns synthetic responses.
+//
+// Any of these changes is a production-code refactor and out of scope for
+// the current test pass. Individual widgets used by these views are already
