## Required Backend Routes

Make sure these routes exist in `routes/web.php`:

```php
// Products
Route::get('/products', [ProductController::class, 'index'])->name('products.index');
Route::get('/products/create', [ProductController::class, 'create'])->name('products.create');
Route::post('/products', [ProductController::class, 'store'])->name('products.store');
Route::get('/products/{product}', [ProductController::class, 'show'])->name('products.show');

// Engagement
Route::post('/products/{product}/upvote', [UpvoteController::class, 'toggle'])
    ->name('products.upvote')->middleware('auth');
Route::post('/products/{product}/bookmark', [BookmarkController::class, 'toggle'])
    ->name('products.bookmark')->middleware('auth');

// Profile
Route::get('/profile/{user}', [ProfileController::class, 'show'])->name('profile.show');
Route::get('/profile/edit', [ProfileController::class, 'edit'])->name('profile.edit');
```

---

## Required Backend Controller Methods

### UpvoteController

```php
<?php

namespace App\Http\Controllers;

use App\Models\Product;
use Illuminate\Http\JsonResponse;

class UpvoteController extends Controller
{
    public function toggle(Product $product): JsonResponse
    {
        $user = auth()->user();

        if ($product->isUpvotedBy($user)) {
            // Remove upvote
            $product->upvotes()->where('user_id', $user->id)->delete();
            $upvoted = false;
        } else {
            // Add upvote
            $product->upvotes()->create(['user_id' => $user->id]);
            $upvoted = true;
        }

        return response()->json([
            'upvoted' => $upvoted,
            'upvotes_count' => $product->upvotes()->count(),
        ]);
    }
}
```

### BookmarkController

```php
<?php

namespace App\Http\Controllers;

use App\Models\Product;
use Illuminate\Http\JsonResponse;

class BookmarkController extends Controller
{
    public function toggle(Product $product): JsonResponse
    {
        $user = auth()->user();

        if ($product->isBookmarkedBy($user)) {
            // Remove bookmark
            $product->bookmarks()->where('user_id', $user->id)->delete();
            $bookmarked = false;
        } else {
            // Add bookmark
            $product->bookmarks()->create(['user_id', $user->id]);
            $bookmarked = true;
        }

        return response()->json([
            'bookmarked' => $bookmarked,
        ]);
    }
}
```

## Responsive Design Guidelines

### Tailwind Breakpoints

```
sm: 640px   (small tablets/large phones)
md: 768px   (tablets)
lg: 1024px  (laptops)
xl: 1280px  (desktops)
2xl: 1536px (large desktops)
```

### Mobile-First Approach

Always write mobile styles first, then add larger breakpoints:

```html
<!-- This is 1 column on mobile, 2 on tablet, 3 on desktop -->
<div class="grid grid-cols-1 md:grid-cols-2 lg:grid-cols-3 gap-6">
    <!-- Content -->
</div>
```

### Common Responsive Patterns

```html
<!-- Hide on mobile, show on desktop -->
<div class="hidden lg:block">Desktop only</div>

<!-- Show on mobile, hide on desktop -->
<div class="lg:hidden">Mobile only</div>

<!-- Responsive padding -->
<div class="px-4 sm:px-6 lg:px-8">Content</div>

<!-- Responsive text -->
<h1 class="text-2xl sm:text-3xl lg:text-4xl">Heading</h1>

<!-- Responsive flex direction -->
<div class="flex flex-col lg:flex-row">
    <div>Item 1</div>
    <div>Item 2</div>
</div>
```

---

## Alpine.js Examples

### Simple Toggle

```html
<div x-data="{ open: false }">
    <button @click="open = !open">Toggle</button>
    <div x-show="open">Content</div>
</div>
```

### Dropdown Menu

```html
<div x-data="{ open: false }" @click.away="open = false">
    <button @click="open = !open">Menu</button>
    <div x-show="open"
         x-transition
         class="absolute">
        <a href="#">Item 1</a>
        <a href="#">Item 2</a>
    </div>
</div>
```

### AJAX Request

```html
<div x-data="{
    loading: false,
    data: null,
    async fetchData() {
        this.loading = true;
        const response = await fetch('/api/endpoint');
        this.data = await response.json();
        this.loading = false;
    }
}">
    <button @click="fetchData()" :disabled="loading">
        Fetch Data
    </button>
    <div x-show="loading">Loading...</div>
    <div x-show="data" x-text="data"></div>
</div>
```

## Performance Optimization

### 1. Lazy Loading Images

All product thumbnails use `loading="lazy"`:

```html
<img src="{{ $product->thumbnail_url }}"
     loading="lazy"
     alt="{{ $product->title }}">
```

### 2. Asset Optimization

```bash
# Development (hot reload)
npm run dev

# Production (minified)
npm run build
```

### 3. CSS Purging

Tailwind automatically purges unused CSS in production based on the `@source` directives in `app.css`.

---

## Accessibility Features

### 1. Semantic HTML

All components use proper semantic HTML:
- `<nav>` for navigation
- `<button>` for interactive elements
- `<a>` for links
- `<main>` for main content

### 2. ARIA Attributes

```html
<!-- Live regions for notifications -->
<div aria-live="assertive">Notification</div>

<!-- Hidden content -->
<span class="sr-only">Visually hidden text for screen readers</span>

<!-- Expanded state -->
<button aria-expanded="true">Menu</button>
```

### 3. Keyboard Navigation

- Modals trap focus
- Tab navigation works everywhere
- ESC key closes modals and dropdowns

### 4. Color Contrast

All text meets WCAG AA standards:
- Primary text: `text-gray-900` on `bg-white`
- Secondary text: `text-gray-600` on `bg-white`
- Buttons have sufficient contrast

---

## Troubleshooting

### Alpine.js Not Working

1. Check browser console for errors
2. Ensure Vite compiled correctly: `npm run dev`
3. Clear browser cache
4. Check that Alpine is initialized in `app.js`

### Tailwind Classes Not Applied

1. Run `npm run dev` or `npm run build`
2. Check `@source` directives in `app.css`
3. Clear browser cache
4. Check for typos in class names

### AJAX Requests Failing

1. Check CSRF token is present
2. Check routes are defined
3. Check controller methods exist
4. Check browser console for errors
5. Verify JSON response format
