🏗️ Architecture

EzQt App follows a hexagonal architecture with three main layers:

src/ezqt_app/
├── domain/          # Contracts, ports, models, errors (no dependencies)
│   ├── ports/       # Abstract interfaces (AppPort, ConfigPort, etc.)
│   ├── models/      # Domain models
│   └── errors/      # Domain exceptions
├── services/        # Adapters implementing domain ports
│   ├── application/ # App lifecycle (AppService, InitService)
│   ├── config/      # Configuration (ConfigService, SettingsService)
│   ├── translation/ # i18n (TranslationService, AutoTranslator)
│   └── ui/          # UI coordination (ThemeService, MenuService)
├── widgets/         # PySide6 presentation layer
│   ├── core/        # Header, Menu, PageContainer
│   └── extended/    # SettingWidgets and advanced components
├── shared/          # Cross-cutting utilities
├── cli/             # Command-line interface
└── app.py           # Main EzQt_App entry point
