### pixel-perfect-implementation

A comprehensive iterative convergence process for achieving pixel-perfect UI implementation from design mocks.

**Location**: `specializations/ux-ui-design/pixel-perfect-implementation.js`

**Purpose**: Takes a design mock and target URL, then iteratively refines the implementation until it matches the mock with configurable quality thresholds.

**Key Features**:
- Multi-dimensional visual scoring (layout, typography, colors, spacing, components, decorative)
- Configurable scoring weights and tolerances
- Iterative convergence with stall detection
- Optional responsive design verification
- Optional accessibility verification
- Human-in-the-loop breakpoints for approval

**Inputs**:
```json
{
  "projectName": "string - Project identifier",
  "mockSource": "string - Path to design mock image",
  "targetUrl": "string - URL of implementation to verify",
  "targetQuality": "number - Target score 0-100 (default: 95)",
  "maxIterations": "number - Maximum refinement iterations (default: 10)",
  "scoringWeights": {
    "layout": 25,
    "typography": 20,
    "colors": 20,
    "spacing": 15,
    "components": 10,
    "decorative": 10
  },
  "tolerances": {
    "pixelDifference": 0.5,
    "colorDelta": 3,
    "spacingPx": 2,
    "fontSizePx": 1
  },
  "viewports": [{ "name": "desktop", "width": 1920, "height": 1080 }],
  "includeResponsive": "boolean - Run responsive verification (default: false)",
  "includeAccessibility": "boolean - Run accessibility verification (default: false)"
}
```

**Phases**:
1. **Mock Analysis** - Extract detailed specifications from design mock
2. **Initial Assessment** - Capture and score current implementation
3. **Iterative Convergence** - Plan → Implement → Capture → Score → Review loop
4. **Responsive Verification** (optional) - Test across viewports
5. **Accessibility Verification** (optional) - WCAG compliance check
6. **Final Quality Gate** - Human approval or automatic pass

**Supporting Agents**:
- `design-mock-analyzer` - Extracts specifications from design mocks
- `visual-qa-scorer` - Multi-dimensional visual quality scoring
- `refinement-planner` - Prioritizes changes for maximum impact
- `ui-implementer` - Executes refinement plan in codebase
- `responsive-verifier` - Tests implementation across viewports
- `accessibility-verifier` - Checks WCAG compliance

**Usage**:
```bash
babysitter run:create \
  --process-id ux-ui-design/pixel-perfect-implementation \
  --entry library/specializations/ux-ui-design/pixel-perfect-implementation.js#process \
  --inputs inputs.json
```

### design-qa

Lightweight design QA process for verifying implementation against design specs.

**Location**: `specializations/ux-ui-design/design-qa.js`

## Conclusion

UX/UI Design and User Experience is a human-centered specialization focused on creating products that users love. Through research, iteration, and attention to detail, UX/UI designers bridge the gap between user needs and business goals, crafting experiences that are both delightful and effective.

Success in this specialization requires empathy, curiosity, creativity, and analytical thinking. It demands continuous learning as tools, technologies, and user expectations evolve. Most importantly, it requires a commitment to putting users first in every decision.
