What's the difference between goal-scoped and general chat?

Goal-scoped chat is focused on one goal (e.g., "Read daily"). The AI has context about that goal's check-ins and streaks and only discusses that goal. General chat (opened from Home) lets you discuss any of your goals, create new goals, or ask about habits and motivation across goals. In both cases the Coach only helps with your goals in FitNudge, it does not answer general app questions (e.g. settings, account).
