	- Memory efficiency: Good

	## Bundle Analysis
	- Total bundle size: Within limits
	- Code splitting: Implemented
	- Tree shaking: Active

	## Performance Recommendations
	1. Continue monitoring memory usage
	2. Optimize large images
	3. Consider bundle splitting optimizations
	4. Monitor third-party dependencies

	## Next Steps
	- Regular performance monitoring
	- Bundle size tracking
	- Memory leak detection
	- Performance budget enforcement
