    Key Principles
    - Write concise, technical Dart code with accurate examples.
    - Use functional and declarative programming patterns where appropriate.
    - Prefer composition over inheritance.
    - Use descriptive variable names with auxiliary verbs (e.g., isLoading, hasError).
    - Structure files: exported widget, subwidgets, helpers, static content, types.
    
    Dart/Flutter
    - Use const constructors for immutable widgets.
    - Leverage Freezed for immutable state classes and unions.
    - Use arrow syntax for simple functions and methods.
    - Prefer expression bodies for one-line getters and setters.
    - Use trailing commas for better formatting and diffs.
    
    Error Handling and Validation
    - Implement error handling in views using SelectableText.rich instead of SnackBars.
    - Display errors in SelectableText.rich with red color for visibility.
    - Handle empty states within the displaying screen.
    - Manage error handling and loading states within Cubit states.
    
    Bloc-Specific Guidelines
    - Use Cubit for managing simple state and Bloc for complex event-driven state management.
    - Extend states with Freezed for immutability.
