Interconnections (Finance ↔ Gamification, Mood)

• Gamification: Logging a transaction awards 5 XP and 1 coin (TransactionService calls GamificationService after create). This ties finance into the same progression as checklist, journal, training, etc.
• Finance achievements: Unlock achievements for finance milestones (see Finance achievements below). FinanceAchievementService is called from TransactionService (transaction count), BudgetService (first budget), SavingsGoalService (goal reached), and FinancialAnalyticsService (under budget month).
• Mood ↔ Spending: Cross-domain analytics (CrossDomainAnalyticsService) computes a mood vs spending correlation: whether lower-mood days tend to have higher or lower spending. When the correlation is strong enough, insights show an interpretation (e.g. "Lower mood days tend to have higher spending (retail therapy pattern)").
