feat: Implement dual theme system with purple/pink and high contrast modes

Browse Source

Added comprehensive theme switching system with two color palettes:

**New Default Theme: Purple/Pink Gradient**
- Primary: #8b52ff (vibrant purple) → #d194e6 (light purple)
- Secondary: #ff7094 (pink) → #ffb3e4 (light pink)
- Modern, energetic gradient aesthetic
- Created purpleTheme.ts with full MUI theme configuration

**High Contrast Theme: Warm Peach (Original)**
- Renamed maternalTheme to highContrastTheme
- Larger text sizes (7.5% increase for accessibility)
- Stronger shadows and bolder fonts
- Optimized for readability and accessibility

**Theme Infrastructure:**
1. **ThemeContext** (contexts/ThemeContext.tsx)
   - Created theme context provider with useThemeContext hook
   - Theme modes: 'standard' (purple) | 'highContrast' (peach)
   - localStorage persistence with key: maternal_theme_preference
   - Prevents flash of wrong theme on load

2. **ThemeRegistry Updates** (components/ThemeRegistry.tsx)
   - Wrapped with ThemeContextProvider
   - Dynamic theme switching via useThemeContext
   - Maintains backward compatibility

3. **Settings Page Toggle** (app/settings/page.tsx)
   - Added theme switcher in Preferences section
   - Switch control with descriptive labels
   - Explains High Contrast benefits
   - Instant theme switching without reload

4. **CSS Variables** (app/globals.css)
   - Added --color-1 through --color-5 for purple gradient
   - Added --warm-1 through --warm-5 for peach palette
   - Available for custom styling

**Features:**
✅ Instant theme switching (no page reload)
✅ Persistent preference across sessions
✅ Accessibility-focused high contrast mode
✅ Modern purple/pink gradient as default
✅ Smooth transitions between themes
✅ All existing components work with both themes

**Files Created:**
- contexts/ThemeContext.tsx
- styles/themes/purpleTheme.ts
- styles/themes/highContrastTheme.ts

**Files Modified:**
- components/ThemeRegistry.tsx
- app/settings/page.tsx
- app/globals.css

Resolves: High Priority Feature #12 - Secondary Color Palette & Accessibility Toggle
