+// MicrosoftRewardsBot class is too large and violates Single Responsibility Principle.
+// Consider extracting into separate modules:
+// - DesktopFlow.ts (Desktop automation logic)
+// - MobileFlow.ts (Mobile automation logic)
+// - SummaryReporter.ts (Conclusion/report generation)
+// - BuyModeHandler.ts (Manual spending mode)
+// - ClusterManager.ts (Worker orchestration)
+// This will improve testability and maintainability.
