## Aktuel Arkitektur Status

### Factory Pattern
- ManagerFactory håndterer manager instantiering
- Proper dependency injection via constructor

### Event-Driven Communication
- EventBus koordinerer kommunikation mellem managers
- NavigationRenderer lytter til WEEK_INFO_UPDATED events
- EventRenderingService reagerer på GRID_RENDERED events

### Separation of Concerns
- Managers håndterer business logic
- Renderers håndterer DOM manipulation
- EventBus håndterer kommunikation
