## 3. HashRouter Implementation

### URL Format

**Shop:**
```
https://woonoow.local/shop
https://woonoow.local/shop#/
```

**Product:**
```
https://woonoow.local/shop#/product/edukasi-anak
```

**Cart:**
```
https://woonoow.local/shop#/cart
```

**Checkout:**
```
https://woonoow.local/shop#/checkout
```

### Why HashRouter?

1. **No WordPress conflicts** - Everything after `#` is client-side
2. **Reliable direct access** - Works from any source
3. **Perfect for sharing** - Email, social media, QR codes
4. **Same as Admin SPA** - Consistent approach
5. **Zero configuration** - No server setup needed

### Implementation

**Changed:** `BrowserRouter` → `HashRouter` in `App.tsx`

```tsx
// Before
import { BrowserRouter } from 'react-router-dom';
<BrowserRouter>...</BrowserRouter>

// After
import { HashRouter } from 'react-router-dom';
<HashRouter>...</HashRouter>
```

That's it! All `Link` components automatically use hash URLs.
