**High Contrast Accessibility Themes Implementation**

## What Was Just Completed

### High Contrast Themes Implementation
Successfully implemented two new high contrast themes for low vision accessibility:

1. **High Contrast Light Theme** (`high-contrast-light`)
   - Pure black text (#000000) on pure white backgrounds (#FFFFFF)
   - 7:1+ contrast ratios (WCAG AAA compliant)
   - Enhanced typography with 600-700 font weights
   - 3px black borders for element definition

2. **High Contrast Dark Theme** (`high-contrast-dark`)
   - Pure white text (#FFFFFF) on pure black backgrounds (#000000)
   - 7:1+ contrast ratios (WCAG AAA compliant)
   - Enhanced typography with 600-700 font weights
   - 3px white borders for element definition

### Files Modified
1. **frontend/src/app/globals.css** - Added complete high contrast theme CSS variables and overrides
2. **frontend/src/app/layout.tsx** - Updated ThemeProvider to include new themes
3. **frontend/src/components/atoms/Icons.tsx** - Added HighContrastLightIcon and HighContrastDarkIcon
4. **frontend/src/components/molecules/ThemeSelector.tsx** - Updated to include new high contrast options
5. **frontend/src/components/organisms/Footer.tsx** - Added accessibility section with theme switching buttons

### Key Features Implemented
- **CSS Variable Architecture**: Follows strict semantic CSS variable system
- **Multiple Access Points**: Theme selector in navigation + footer accessibility buttons
- **Enhanced Focus Indicators**: 4px yellow outlines for keyboard navigation
- **Complete Text Visibility**: Fixed all invisible text issues (buttons, navigation, CTA sections)
- **WCAG AAA Compliance**: Maximum contrast ratios for low vision users
- **Performance Optimized**: CSS-only theme switching without JavaScript re-rendering

### Technical Highlights
- Eliminated all blue elements in high contrast modes for true contrast
- Fixed navigation button text visibility issues
- Fixed CTA section text and button contrast
- Added comprehensive button styling overrides
- Maintained next-themes integration for persistence

## Current State
The high contrast accessibility implementation is now complete and fully functional. Users can:
- Access themes via navigation theme selector dropdown
- Switch directly from footer accessibility buttons  
- Experience true high contrast with maximum visibility
- Navigate with enhanced keyboard focus indicators

## Next Steps
Ready for git commit and deployment.
