Architecture Overview

BitTrek follows the MVVM architecture, ensuring a clean separation of concerns and testability:

• View: Handles the UI components and binds to the ViewModel.
• ViewModel: Serves as the intermediary between the Model and View, implementing business logic and exposing data to the UI.
