## Technical Notes

### Routes
```php

Route::get('/posts', \App\Livewire\Posts\Index::class)->name('posts.index');
Route::get('/posts/{post}', \App\Livewire\Posts\Show::class)->name('posts.show');
```

### Posts Index Component
```php
<?php

use App\Models\Post;
use Livewire\Volt\Component;
use Livewire\WithPagination;

new class extends Component {
    use WithPagination;

    public function with(): array
    {
        return [
            'posts' => Post::published()
                ->latest()
                ->paginate(10),
        ];
    }
}; ?>

<div class="max-w-4xl mx-auto">
    <flux:heading>{{ __('posts.title') }}</flux:heading>

    <div class="mt-8 space-y-6">
        @forelse($posts as $post)
            <article class="bg-cream p-6 rounded-lg shadow-sm hover:shadow-md transition-shadow">
                <h2 class="text-xl font-semibold text-navy">
                    <a href="{{ route('posts.show', $post) }}" class="hover:text-gold">
                        {{ $post->title }}
                    </a>
                </h2>

                <time class="text-sm text-charcoal/70 mt-2 block">
                    {{ $post->created_at->translatedFormat('d F Y') }}
                </time>

                <p class="mt-3 text-charcoal">
                    {{ $post->excerpt }}
                </p>

                <a href="{{ route('posts.show', $post) }}" class="text-gold hover:underline mt-4 inline-block">
                    {{ __('posts.read_more') }} &rarr;
                </a>
            </article>
        @empty
            <p class="text-center text-charcoal/70 py-12">
                {{ __('posts.no_posts') }}
            </p>
        @endforelse
    </div>

    {{ $posts->links() }}
</div>
```

### Post Show Component
```php
<?php

use App\Models\Post;
use Livewire\Volt\Component;

new class extends Component {
    public Post $post;

    public function mount(Post $post): void
    {
        // Only show published posts
        abort_unless($post->status === 'published', 404);

        $this->post = $post;
    }
}; ?>

<article class="max-w-3xl mx-auto">
    <header class="mb-8">
        <flux:heading>{{ $post->title }}</flux:heading>

        <time class="text-charcoal/70 mt-2 block">
            {{ $post->created_at->translatedFormat('l, d F Y') }}
        </time>
    </header>

    <div class="prose prose-lg prose-navy max-w-none">
        {!! $post->body !!}
    </div>

    <footer class="mt-12 pt-6 border-t border-charcoal/20">
        <a href="{{ route('posts.index') }}" class="text-gold hover:underline">
            &larr; {{ __('posts.back_to_posts') }}
        </a>
    </footer>
</article>
```

### Prose Styling
```css
/* In app.css */
.prose-navy {
    --tw-prose-headings: theme('colors.navy');
    --tw-prose-links: theme('colors.gold');
    --tw-prose-bold: theme('colors.navy');
}

.prose-navy a {
    text-decoration: underline;
}

.prose-navy a:hover {
    color: theme('colors.gold-light');
}
```

## Testing Requirements

### Feature Tests
```php
use App\Models\Post;
use Livewire\Volt\Volt;

test('posts listing page shows only published posts', function () {
    Post::factory()->create(['status' => 'published', 'title_en' => 'Published Post']);
    Post::factory()->create(['status' => 'draft', 'title_en' => 'Draft Post']);

    $this->get(route('posts.index'))
        ->assertOk()
        ->assertSee('Published Post')
        ->assertDontSee('Draft Post');
});

test('posts displayed in reverse chronological order', function () {
    $older = Post::factory()->create(['status' => 'published', 'created_at' => now()->subDays(5)]);
    $newer = Post::factory()->create(['status' => 'published', 'created_at' => now()]);

    $this->get(route('posts.index'))
        ->assertOk()
        ->assertSeeInOrder([$newer->title, $older->title]);
});

test('posts listing page paginates results', function () {
    Post::factory()->count(15)->create(['status' => 'published']);

    $this->get(route('posts.index'))
        ->assertOk()
        ->assertSee('Next'); // pagination link
});

test('individual post page shows full content', function () {
    $post = Post::factory()->create(['status' => 'published']);

    $this->get(route('posts.show', $post))
        ->assertOk()
        ->assertSee($post->title)
        ->assertSee($post->body);
});

test('individual post page returns 404 for unpublished posts', function () {
    $post = Post::factory()->create(['status' => 'draft']);

    $this->get(route('posts.show', $post))
        ->assertNotFound();
});

test('individual post page returns 404 for non-existent posts', function () {
    $this->get(route('posts.show', 999))
        ->assertNotFound();
});
```

### Language/RTL Tests
- [ ] Arabic content displays correctly with RTL direction
- [ ] English content displays correctly with LTR direction
- [ ] Date formatting respects locale (`translatedFormat`)
- [ ] Back link text displays in current language

### Responsive Tests
- [ ] Mobile layout renders correctly (single column, touch-friendly)
- [ ] Tablet layout renders correctly
- [ ] Typography remains readable at all breakpoints

### Key Test Scenarios
| Scenario | Expected Result |
|----------|-----------------|

| Visit /posts with no posts | Shows "no posts" message |
| Visit /posts/{id} for published post | Shows full post content |
| Visit /posts/{id} for draft post | Returns 404 |
| Switch language on posts page | Content displays in selected language |

## Definition of Done

- [ ] Posts listing page works
- [ ] Individual post page works
- [ ] Only published posts visible
- [ ] Reverse chronological order
- [ ] Excerpts display correctly
- [ ] Full content renders properly
- [ ] Language-appropriate content shown
- [ ] Mobile responsive
- [ ] RTL support

## Dependencies

- **Story 5.1:** Post creation (provides Post model with `published()` scope, `title`, `body`, `excerpt` accessors - see Database Schema and Post Model sections)
- **Epic 1:** Base UI, navigation, bilingual infrastructure

## Estimation

**Complexity:** Medium
**Estimated Effort:** 3-4 hours
