        {{ __('navigation.home') }}
    </flux:navbar.link>

        {{ __('navigation.booking') }}
    </flux:navbar.link>
    <flux:navbar.link href="/posts" :active="request()->is('posts*')">
        {{ __('navigation.posts') }}
    </flux:navbar.link>

    @auth
        <flux:navbar.link href="/dashboard" :active="request()->is('dashboard*')">
            {{ __('navigation.dashboard') }}
        </flux:navbar.link>
        <form method="POST" action="{{ route('logout') }}" class="inline">
            @csrf
            <flux:navbar.link
                href="{{ route('logout') }}"
                onclick="event.preventDefault(); this.closest('form').submit();"
            >
                {{ __('navigation.logout') }}
            </flux:navbar.link>
        </form>
    @else
        <flux:navbar.link href="/login" :active="request()->is('login')">
            {{ __('navigation.login') }}
        </flux:navbar.link>
    @endauth
</flux:navbar.links>
```

## QA Results

### Review Date: 2025-12-26

### Reviewed By: Quinn (Test Architect)

### Risk Assessment

**Risk Level: Low-Medium**
- No auth/payment/security files directly modified
- Tests added (27 tests covering all acceptance criteria)
- Story has extensive AC (18+ criteria) - but all well-covered
- Clean diff with focused UI components
- No previous gate failures

### Code Quality Assessment

**Overall: Excellent**

The implementation demonstrates high-quality code practices:

1. **Component Architecture**: Clean separation of concerns with dedicated components:
   - `navigation.blade.php` - Self-contained navigation with Alpine.js state
   - `footer.blade.php` - Reusable footer component
   - `logo.blade.php` - Logo with graceful fallback
   - `layouts/public.blade.php` - Clean layout wrapper
   - `language-toggle.blade.php` - Standalone language switcher

2. **Mobile-First Design**: Properly implements responsive patterns with `md:` breakpoints and mobile menu toggle via Alpine.js

3. **Accessibility**:
   - ARIA attributes present (`aria-expanded`, `aria-label`)
   - Touch-friendly targets (44px minimum via `min-h-[44px]`)
   - Proper semantic HTML (`<nav>`, `<address>`, `<footer>`)

4. **RTL/LTR Support**: Correctly uses `border-s-2` for logical start border that works in both directions

5. **Testing Strategy**: Excellent use of `data-test` attributes for reliable test selectors
