## API Integration

### Regions Service (`src/services/regions/index.ts`)
Uses existing API endpoints:
- `GET /api/regions` - Fetches all regions with countries

### Services Integration
- Existing Service interface has `region_ids: number[]` field
- Region detail page filters services: `services.filter(s => s.region_ids.includes(regionId))`

### Projects Integration
- Existing Project interface has `region_ids: number[]` field
- Region detail page filters projects: `projects.filter(p => p.region_ids.includes(regionId))`

## Styling & UX

### Design Consistency
- Uses existing petro-card, petro-section, and petro-container classes
- Consistent with existing service and project card designs
- Framer Motion animations throughout:
  - Fade-in animations on scroll
  - Hover lift effects on cards
  - Smooth transitions

### Color Scheme
- Primary colors: accent, primary, secondary, foreground, muted-foreground
- Gradient backgrounds for region headers
- Consistent with existing design system

## Database/Backend Requirements

Make sure your backend database has:
1. **Regions table** with fields:
   - `id` (number)
   - `name` (string)
   - `countries` (array/JSON of country names)
   - `sort_order` (number)
   - `created_at` (timestamp)
   - `updated_at` (timestamp)

2. **Services** have `region_ids` field (array of region IDs)
3. **Projects** have `region_ids` field (array of region IDs)
