## Summary

### Files Created

**1. Checkout Component** - `/Users/fabianwesner/Herd/shop/app/Livewire/Storefront/Checkout/Index.php`

A multi-step Livewire component with 4 steps (Contact, Address, Delivery, Payment). Key behaviors:
- `mount()` - Gets cart from session via `CartService::getOrCreateForSession`, redirects to `/cart` if empty, creates checkout via `CheckoutService::createCheckout`, applies discount code from session
- `submitContact()` - Validates email, saves to checkout, advances to step 2
- `submitAddress()` - Validates all address fields, calls `CheckoutService::setAddress()`, loads shipping rates via `ShippingCalculator::getAvailableRates()`, advances to step 3
- `submitShipping()` - Validates rate selection, calls `CheckoutService::setShippingMethod()`, loads totals from `totals_json`, advances to step 4
- `submitPayment()` - Validates payment method and card fields (if credit card), calls `selectPaymentMethod()` then `completeCheckout()`, clears session on success and redirects to confirmation, catches `PaymentFailedException` and shows error
- `goToStep()` - Only allows navigating backwards

**2. Checkout View** - `/Users/fabianwesner/Herd/shop/resources/views/livewire/storefront/checkout/index.blade.php`

Two-column layout (60/40 on desktop, stacked on mobile):
- Left column: Step indicator with numbered circles, conditionally rendered step forms using Flux UI components (input, button, field, label)
- Right column: Sticky order summary sidebar showing cart items, and totals (subtotal, discount, shipping, tax, total) once calculated
- Shipping rates shown as styled radio buttons with name and price
- Payment method selection with conditional credit card fields
- Error display for payment failures

**3. Confirmation Component** - `/Users/fabianwesner/Herd/shop/app/Livewire/Storefront/Checkout/Confirmation.php`

- `mount(string $orderNumber)` - Finds order by `order_number` with eager-loaded lines and payments, aborts 404 if not found
- No authentication required (guest checkout support)

**4. Confirmation View** - `/Users/fabianwesner/Herd/shop/resources/views/livewire/storefront/checkout/confirmation.blade.php`

- Green checkmark success icon
- "Thank you for your order!" heading with order number and email
- Bank transfer details callout (conditionally shown) with Mock Bank AG, IBAN, BIC, reference, and 7-day deadline
- Order items list with title, quantity, and line total
- Two-column grid: shipping address card and payment/totals card
- "Continue Shopping" button

### File Modified

**5. Routes** - `/Users/fabianwesner/Herd/shop/routes/web.php`

Added two use statements and a new route group:
```php
use App\Livewire\Storefront\Checkout\Confirmation as CheckoutConfirmation;
use App\Livewire\Storefront\Checkout\Index as CheckoutIndex;

// Checkout routes (accessible without authentication for guest checkout)
Route::middleware(['store.resolve'])->group(function () {
    Route::get('/checkout', CheckoutIndex::class)->name('checkout');
    Route::get('/checkout/confirmation/{orderNumber}', CheckoutConfirmation::class)->name('checkout.confirmation');
});
```

### Test Files Created

**7.** `/Users/fabianwesner/Herd/shop/tests/Feature/Livewire/Storefront/Checkout/CheckoutConfirmationTest.php` - 5 tests covering: valid order display, 404 for missing order, bank transfer details, discount display, and shipping address display.

All 54 checkout-related tests pass (36 existing + 18 new, 150 assertions).</result>
