-## Architecture
-
-The app follows the modern layered architecture recommended by Google. The UI layer observes
-immutable state from ViewModels. Business logic is encapsulated in use case classes within the
-domain layer, which interact with repositories in the data layer. Each screen now exposes its
-operations through a small set of use cases. This pattern was inspired by the
-[Android Clean Architecture](https://github.com/android10/Android-CleanArchitecture) sample but
-implemented in a simplified form to avoid adding heavy dependencies. The result keeps the UI
-simple and ensures a clear separation of concerns across the whole app.
-
-For detailed guidance, see [Recommendations for Android architecture](docs/core/android-architecture-recommendations.md).
