"""EU-Utility Core Package.

This package contains the core functionality for EU-Utility, including:
- Plugin management and base classes
- API services (Nexus, HTTP, OCR, etc.)
- UI components and theming
- Event system and background tasks
- Data persistence and settings

Quick Start:
    from core.api import get_api
    from core.event_bus import get_event_bus, LootEvent
    
    api = get_api()
    bus = get_event_bus()

Architecture:
    - **api/**: Three-tier API system (PluginAPI, WidgetAPI, ExternalAPI)
    - **services/**: Core services (OCR, screenshot, audio, etc.)
    - **ui/**: UI components and views
    - **utils/**: Utility modules (styles, security, etc.)

See individual modules for detailed documentation.
