Route Model Binding: Cleaner Controller Code

Route model binding removes repetitive database lookups from your controllers.

## Traditional approach

```php
public function show($id) {
  $post = Post::findOrFail($id);
}
```

## With model binding

```php
public function show(Post $post) {
  return view('posts.show', compact('post'));
}
```

Route:

```php
Route::get('/posts/{post}', [PostController::class, 'show']);
```

Laravel sees {post} and loads the model automatically.

## Flow

  A[/posts/5] --> B[Router]
  B --> C[Load Post]
  C --> D[Controller(Post)]
```

This keeps controllers shorter and more readable.

In the next tutorial, we will secure mass assignment using $fillable.
