- **Refresh Token TTL**: 14 hari (20160 menit)

### Role-Based Access Control (RBAC)
Menggunakan middleware `CheckRole` untuk protect routes:

## 🎨 Custom Calendar Engine

**Implementasi logic khusus** untuk booking validation:

### Validasi Ketersediaan Slot:
```php
✅ Check jadwal terapis berdasarkan day_of_week
✅ Check booking bentrok dengan therapist_id
✅ Check booking bentrok dengan room_id
✅ Handle durasi layanan dengan time calculation
✅ Concurrency control dengan lockForUpdate()
✅ Prevent double booking dengan database transaction
```

### Endpoint:
- `POST /customer/bookings/check-availability`
- Returns: `available_therapists[]`, `available_rooms[]`, `slot_available: boolean`
