 The server periodically (every second) sends JSON-encoded messages to all connected clients to update them on the current state of the Pomodoro session. These messages contain the following fields:
 
-- mode: Indicates the current phase of the Pomodoro session ("Work", "ShortBreak", "LongBreak", "End" or "Idle").
+- mode: Indicates the current phase of the Pomodoro session ("Focus", "ShortBreak", "LongBreak", "End" or "Idle").
   - "End" is send only once, after all sessions are finished
