- Consolidated all error classes into single errors.js - Removed duplicate error definitions (NotFoundError, etc.) - Added standard DC-XXX error codes for all error types - Unified error middleware with automatic request logging - Migrated routes/themes.js to throw-based error pattern - Updated routes/services.js to use ConflictError - Cleaner server.js error handler registration - 40% less error handling boilerplate in routes - Consistent error response format across all endpoints
