+└─────────────────────────────────────┘
+```
+
+### Mobile Layout
+Single column, stacked sections with sticky order summary at bottom.
+
+---
+
+## Technical Implementation
+
+### State Management
+
+```typescript
+// Form state (existing)
+const [shippingAddress, setShippingAddress] = useState<AddressForm>({...});
+const [billingAddress, setBillingAddress] = useState<AddressForm>({...});
+const [sameAsShipping, setSameAsShipping] = useState(true);
+
+// New state
+const [paymentMethod, setPaymentMethod] = useState<string>("cod");
+const [errors, setErrors] = useState<ValidationErrors>({
+  contact: null,
+  shipping: null,
+  billing: null,
+  shippingMethod: null,
+  general: null,
+});
+```
+
+### Debounced Shipping Method Fetching
+
+```typescript
+useEffect(() => {
+  if (!isAddressComplete(shippingAddress)) return;
+  
+  const timer = setTimeout(() => {
+    fetchShippingMethods();
+  }, 500); // 500ms debounce
+  
+  return () => clearTimeout(timer);
+}, [shippingAddress]);
+```
+
+### Validation Schema
+
+```typescript
+const validationRules = {
+  email: (value) => /^[^\s@]+@[^\s@]+\.[^\s@]+$/.test(value),
+  phone: (value) => {
+    // Country-specific validation
+    // Serbia: +381 XX XXX XXXX
+    // Bosnia: +387 XX XXX XXX
+    // etc.
+  },
+  required: (value) => value.trim().length > 0,
+  postalCode: (value, country) => {
+    // Country-specific postal code validation
+  },
+};
+```
+
+### API Call Sequence
+
+**Optimized Flow (parallel + sequential):**
+
+```
+Step 1: Validation (client-side)
+  ├─ Validate all fields
+  └─ Show inline errors
+
+Step 2: Parallel Independent Calls
+  ├─ Update Email
+  └─ Update Shipping Address
+  (Both can run simultaneously)
+
+Step 3: Conditional Call
+  └─ Update Billing Address (if different from shipping)
+
+Step 4: Sequential Dependent Calls
+  ├─ Update Shipping Method
+  ├─ Update Metadata (phone, language, payment method)
+  └─ Complete Checkout
+
+Total: 4 sequential steps vs current 7+
+```
+
+### Error Handling Strategy
+
+**Field-level:**
+- Real-time validation on blur
+- Visual indicators (red border, error message)
+- Prevent submit if validation fails
+
+**Section-level:**
+- Group errors by section
+- Show section header in red if has errors
+- Expand section if collapsed and has errors
+
+**Form-level:**
+- On submit: validate all fields
+- If errors: scroll to first error, show summary
+- If API error: show in relevant section, preserve data
+
+**API-level:**
+- Map Saleor errors to form fields when possible
+- Generic error: show at top of form
+- Network error: show retry button
+

+- [ ] Test existing flow still works
+
+### Phase 2: Dynamic Shipping Methods (Day 3)
+- [ ] Implement debounced fetching
+- [ ] Add loading states
+- [ ] Display shipping methods inline
+- [ ] Update total when method selected
+
+### Phase 3: Validation & Error Handling (Day 4)

+- [ ] Verify order created in Saleor
+- [ ] Verify emails sent
+- [ ] Change shipping method, verify total updates
+- [ ] Change address, verify shipping methods refetch
+
+### Validation Tests
+- [ ] Submit with empty email → email error
+- [ ] Submit with empty phone → phone error
+- [ ] Submit with invalid email format → format error
+- [ ] Submit with invalid phone → format error
+- [ ] Submit with empty required fields → field errors
+- [ ] Submit without selecting shipping method → shipping error
+
+### Edge Cases
+- [ ] Slow network (test debouncing)
+- [ ] No shipping methods available
+- [ ] API failure during submission

+5. **Production:** Merge to master and deploy
+
+---
+
+## Success Metrics
+
+- **Conversion Rate:** Should increase (fewer steps = less drop-off)
+- **Time to Complete:** Should decrease (single page vs two phases)
+- **Error Rate:** Should decrease (better validation)
+- **Mobile Completion:** Should improve (optimized for mobile)
+
+---
+
+## Future Enhancements (Out of Scope)
+
+- [ ] Save addresses for logged-in users
+- [ ] Address autocomplete (Google Maps)
+- [ ] Multiple payment methods (Stripe, etc.)
+- [ ] Guest checkout improvements
+- [ ] Order notes/comments field
+- [ ] Gift wrapping options
+- [ ] Promo code input
+
+---
+
+## Notes
+
+- Phone number is **strictly required** - validate format per country
+- Keep existing checkout success page
+- Maintain multi-language support
+- Ensure analytics tracking works
+- Don't break existing cart functionality

+# Manoon Storefront Test Suite
+
+Comprehensive test suite for the ManoonOils storefront with focus on webhooks, commerce operations, and critical paths.
+
+## 🎯 Coverage Goals
+
+- **Critical Paths**: 80%+ coverage
+- **Webhook Handlers**: 100% coverage
+- **Email Services**: 90%+ coverage
+- **Analytics**: 80%+ coverage
+
+## 🧪 Test Structure

+```
+
+## 🚀 Running Tests
+
+### Unit & Integration Tests (Vitest)
+
+```bash
+# Run tests in watch mode
+npm test
+
+# Run tests once
+npm run test:run
+
+# Run with coverage report
+npm run test:coverage
+
+# Run with UI
+npm run test:ui
+```
+
+### E2E Tests (Playwright)
+
+```bash
+# Run all E2E tests
+npm run test:e2e
+
+# Run with UI mode
+npm run test:e2e:ui
+
+# Run specific test
+npx playwright test tests/critical-paths/checkout-flow.spec.ts
+```
+
+## 📊 Test Categories
+
+### 🔥 Critical Tests (Must Pass)
+
+1. **Webhook Handler Tests**
+   - ORDER_CONFIRMED: Sends emails + analytics
+   - ORDER_CREATED: No duplicate emails/analytics
+   - ORDER_FULFILLED: Tracking info included
+   - ORDER_CANCELLED: Cancellation reason included
+   - ORDER_FULLY_PAID: Payment confirmation
+
+2. **Email Service Tests**
+   - Correct translations (SR, EN, DE, FR)
+   - Price formatting (no /100 bug)
+   - Admin vs Customer templates
+   - Address formatting
+
+3. **Analytics Tests**
+   - Revenue tracked once per order
+   - Correct currency (RSD not USD)
+   - Error handling (doesn't break order flow)
+
+### 🔧 Integration Tests
+
+- Full checkout flow
+- Cart operations
+- Email template rendering
+- API error handling
+
+## 🎭 Mocking Strategy
+
+- **Resend**: Mocked (no actual emails sent)
+- **OpenPanel**: Mocked (no actual tracking in tests)
+- **Saleor API**: Can use real instance for integration tests (read-only)
+
+## 📈 Coverage Reports
+
+Coverage reports are generated in multiple formats:
+- Console output (text)
+- `coverage/coverage-final.json` (JSON)
+- `coverage/index.html` (HTML report)
+
+Open `coverage/index.html` in browser for detailed view.
+
+## 🔍 Debugging Tests
+
+```bash
+# Debug specific test
+npm test -- --reporter=verbose src/__tests__/unit/services/AnalyticsService.test.ts
+
+# Debug with logs
+DEBUG=true npm test
+```
+
+## 📝 Adding New Tests
+
+1. Create test file: `src/__tests__/unit|integration/path/to/file.test.ts`
+2. Import from `@/` alias (configured in vitest.config.ts)
+3. Use fixtures from `src/__tests__/fixtures/`
+4. Mock external services
+5. Run tests to verify
+
+## 🚧 Current Limitations
+
+- No CI/CD integration yet (informational only)
+- E2E tests need Playwright browser installation
+- Some tests use mocked data instead of real Saleor API
+
+## ✅ Test Checklist
+
+Before deploying, ensure:
+- [ ] All webhook tests pass
+- [ ] Email service tests pass
+- [ ] Analytics tests pass
+- [ ] Coverage >= 80% for critical paths
+- [ ] No console errors in tests
