## UX Audit Results
### Summary
- **Target**: [component/screen name]
- **Overall Score**: [X/100]
- **Findings**: [X critical, X major, X minor, X cosmetic]
### Critical & Major Findings
[Sorted by severity, then by frequency]
### Strengths
[What the design does well]
### Recommendations
[Prioritized action items with effort estimates]
