Analyze this UI screenshot for usability issues.

**Image**: [attached or path]

**Focus Areas**:
1. Visual hierarchy - Is the most important content prominent?
2. Affordances - Do interactive elements look clickable/tappable?
3. Feedback - Is system status clearly communicated?
4. Consistency - Do similar elements behave similarly?
5. Error prevention - Are destructive actions guarded?

**Output Format**:
For each issue found:
- **Location**: Where in the UI
- **Issue**: What the problem is
- **Principle**: Which design principle it violates
- **Severity**: CRITICAL/HIGH/MEDIUM/LOW
- **Recommendation**: Specific fix

Audit this UI for WCAG 2.1 AA compliance.

**Image**: [attached or path]

**Checklist**:
1. **Perceivable**
   - [ ] Text contrast >= 4.5:1 (WCAG 1.4.3)
   - [ ] Non-text contrast >= 3:1 (WCAG 1.4.11)
   - [ ] Information not conveyed by color alone (WCAG 1.4.1)
   - [ ] Text resizable to 200% (WCAG 1.4.4)

2. **Operable**
   - [ ] Keyboard accessible (WCAG 2.1.1)
   - [ ] No keyboard traps (WCAG 2.1.2)
   - [ ] Focus visible (WCAG 2.4.7)
   - [ ] Touch targets >= 44x44px (WCAG 2.5.5)

3. **Understandable**
   - [ ] Labels present for inputs (WCAG 3.3.2)
   - [ ] Error identification clear (WCAG 3.3.1)
   - [ ] Instructions available (WCAG 3.3.2)

4. **Robust**
   - [ ] Valid structure implied (headings, regions)

**Output Format**:
| Criterion | Status | Notes | Fix |
|-----------|--------|-------|-----|
| 1.4.3 | PASS/FAIL | Details | Recommendation |

Compare this implementation against the design system.

**Implementation Image**: [attached or path]
**Design System Reference**: [tokens, components, patterns]

**Validation Points**:
1. **Colors**
   - Primary, secondary, accent colors
   - Semantic colors (success, warning, error)
   - Background and surface colors

2. **Typography**
   - Font family usage
   - Size scale adherence
   - Weight usage (regular, medium, bold)
   - Line height consistency

3. **Spacing**
   - Margin scale (4, 8, 16, 24, 32, 48...)
   - Padding consistency
   - Gap between elements

4. **Components**
   - Button variants (primary, secondary, ghost)
   - Input styles (default, focus, error, disabled)
   - Card patterns

5. **Elevation**
   - Shadow levels
   - Border usage
   - Layer hierarchy

**Output Format**:
| Element | Expected | Actual | Deviation |
|---------|----------|--------|-----------|
| Button BG | #2563EB | #3B82F6 | Wrong shade |

Compare the implementation screenshot to the original design.

**Design Reference**: [Figma export or mockup]
**Implementation**: [Screenshot of built UI]

**Comparison Points**:
1. Layout and positioning accuracy
2. Color fidelity
3. Typography matching
4. Spacing precision
5. Component rendering
6. Responsive behavior (if multiple sizes)

**Output Format**:
## Match Analysis

**Overall Fidelity**: X/10

### Exact Matches
- [List elements that match perfectly]

### Deviations
| Element | Design | Implementation | Impact | Fix |
|---------|--------|----------------|--------|-----|
| CTA Button | #2563EB | #3B82F6 | Visual | Change to design color |

### Missing Elements
- [Elements in design but not in implementation]

### Extra Elements
- [Elements in implementation but not in design]
