Research direction

Start with the MainActivity.kt reproduction in the linked repository and run a debug launch using React Native 0.72.6. Trace the reported path through DefaultDevLoadingViewImplementation and compare it with the custom activity restart sequence; done means establishing a scoped, reproducible framework issue or documenting why the report does not identify a framework change.
