```

## Content Management

### Bilingual Content Structure

```typescript
const content = {
  ar: {
    hero: {
      /* Arabic content */
    },
    features: {
      /* Arabic features */
    },
    // ... other sections
  },
  en: {
    hero: {
      /* English content */
    },
    features: {
      /* English features */
    },
    // ... other sections
  },
};
```

### Dynamic Tab System

- **Reminders Tab**: Timeline visualization and feature list
- **Chat Tab**: Conversation management features
- **Broadcast Tab**: Segmentation and campaign types
- **Status Tab**: Update types and triggers

## Styling & Design

### Color Palette

- **Primary**: `brand-green` (emerald/teal family)
- **Accent**: `brand-greenHover`
- **Neutral**: `brand-ink`, `brand-sand`
- **Dark Mode**: `slate-900`, `slate-800` backgrounds

### Animations

- **Fade In**: Tab content transitions
- **Hover Effects**: Card lift and scale transforms
- **Transitions**: Smooth color and transform changes

### Responsive Design

- **Mobile**: Full-width stacked layout
- **Tablet**: 2-column grids
- **Desktop**: 3-4 column grids, hover effects

## Accessibility

### ARIA Implementation

```html
<div role="tablist">
  <button role="tab" aria-selected="true" aria-controls="panel-id">
    Tab Label
  </button>
</div>
<div role="tabpanel" id="panel-id">Tab Content</div>
```

### Keyboard Navigation

- Tab navigation between interactive elements
- Enter/Space for button activation
- Arrow keys for tab selection (future enhancement)

## Performance Optimizations

### Static Generation

- Pre-rendered at build time
- ISR with 1-hour revalidation
- No runtime API calls

### Bundle Size

- Minimal JavaScript (only tab switching)
- Static content reduces payload
- Lazy loading for images (future)

## Testing

### Test Coverage

- **Unit Tests**: Component rendering, language switching
- **Integration Tests**: Tab functionality, link navigation
- **E2E Tests**: Full user journeys
- **Cross-Browser**: Chrome, Firefox, Safari, Mobile browsers

### Test Files

```
/tests/messages-page.spec.ts
/tests/README.md
/playwright.config.ts
```

### Running Tests

```bash
# Run all tests
npm test

# Run messages page tests only
npm run test:messages

# Interactive UI mode
npm run test:ui

# Generate test report
npm run test:report
```

## Security Considerations

### Current Implementation

- ✅ Static content (no user input)
- ✅ TypeScript type safety
- ✅ React automatic escaping
- ✅ No external API calls

### Recommendations

- Add CSP headers
- Implement security headers (X-Frame-Options, HSTS)
- Regular dependency updates
- Input validation for future dynamic features
