# IFocusModeService

- File ID: file:xs3ks1:ifocusmodeservice-cs
- Path: NexusReader.UI.Shared/Services/IFocusModeService.cs
- Role: service
- Layer: frontend

## Purpose

Defines the IFocusModeService interface for UI focus mode control (querying state, initialization, toggling, and change notifications).

## Key Details

Interface is declaration-only; concrete implementations are expected to handle persistence, event invocation, and startup initialization behavior.

## Symbols

- IFocusModeService: Defines the IFocusModeService interface for UI focus mode control (querying state, initialization, toggling, and change notifications).
- IsFocusModeActive(): Property getter that indicates whether focus mode is currently active.
- OnFocusModeChanged(): Event raised when focus mode changes, subscribers receive an asynchronous notification.
- InitializeAsync(): Asynchronously initializes the focus mode service (e.g., load persisted state or perform startup tasks).
- ToggleAsync(): Asynchronously toggles the focus mode state and typically notifies subscribers.
- IFocusModeService: Contract for a UI-level service that manages focus mode state, initialization, toggling, and change notifications.
