Create comprehensive demo showing what running the quality validator
on the React app would produce:

- Overall quality score: 85.5/100 (B grade)
- Component breakdown (Code Quality, Coverage, Architecture, Security)
- Detailed findings for each analysis dimension
- Top 5 coverage gaps identified
- High-priority recommendations for improvement
- Sample JSON/HTML/CSV report formats
