## 🚀 DEPLOYMENT STEPS

### 1. Copy Files (5 min)
```
cp /api/controllers/*.php → /your-server/api/controllers/
cp /api/services/*.php → /your-server/api/services/
cp /api/index.php → /your-server/api/index.php
cp /config/config.php → /your-server/config/config.php
cp /assets/api-client.js → /your-server/assets/api-client.js
```

### 2. Update Configuration (10 min)
Edit `/config/config.php`:
```php
'database' => [
    'host' => 'your-host',
    'name' => 'your-db',
    'user' => 'your-user',
    'password' => 'your-password'
],
'email' => [
    'host' => 'smtp.gmail.com',
    'username' => 'your-email@gmail.com',
    'password' => 'app-password'
],
'stripe' => [
    'public_key' => 'pk_live_...',
    'secret_key' => 'sk_live_...'
]
```

### 3. Import Database (5 min)
```sql
mysql -u user -p database < backup.sql
```

### 4. Update Frontend (20 min)
Include API client in your pages:
```html
<script src="/hostiva/assets/api-client.js"></script>
```

Use API instead of localStorage:
```javascript
// Before: localStorage
// After:
const result = await API.createBooking(data);
if (result.success) {
    // Booking created in database
}
```

### 5. Test All Systems (30 min)
- Login test
- Create booking test
- Generate invoice test
- Send email test
- Process payment test
