feat: implement accessibility tools and named colors explorer
Add comprehensive accessibility features and color naming:
**Color Utilities (lib/utils/color.ts):**
- getRelativeLuminance() - WCAG 2.1 luminance calculation
- getContrastRatio() - Contrast ratio between two colors
- hexToRgb() - Convert hex to RGB
- checkWCAGCompliance() - AA/AAA compliance checker
- Full WCAG 2.1 specification implementation
**New UI Component:**
- Badge component - Status indicators
- Variants: default, success, warning, destructive, outline
- Used for pass/fail indicators
- Accessible focus states
**Accessibility Pages:**
1. Contrast Checker (/accessibility/contrast)
- Dual color pickers (foreground/background)
- Real-time contrast ratio calculation
- Live text preview with both colors
- WCAG 2.1 compliance display:
- Level AA: Normal text (4.5:1), Large text (3:1), UI (3:1)
- Level AAA: Normal text (7:1), Large text (4.5:1)
- Pass/Fail badges for each criterion
- Swap colors button
- Visual feedback with color-coded results
2. Accessibility Dashboard (/accessibility)
- Overview of all accessibility tools
- Feature cards with icons
- Educational content about WCAG 2.1
- Standards explanation (AA vs AAA)
- Links to each tool
**Named Colors Page (/names):**
- Display all 148 CSS/X11 named colors
- Search by name or hex value
- Sort options (name, hue)
- Responsive grid layout (2-6 columns)
- Click to copy color
- Color name and hex display
- Loading and error states
- Empty state for no results
- Real-time filtering
**Batch Operations Page (/batch):**
- Placeholder "Coming Soon" page
- Feature preview list
- Planned capabilities description
- Professional coming soon message
**Features Implemented:**
- Real WCAG calculations (not approximations)
- Live contrast ratio updates
- Interactive color swapping
- Comprehensive compliance checking
- Educational content
- Named colors from API
- Search and filtering
- Responsive layouts
**Build Status:**
✅ 11 pages successfully rendering
✅ All TypeScript checks passing
✅ No build errors
All major sections now have functional or placeholder pages!
Next: Polish, testing, and additional enhancements.
