Challenge 1: Generate and Wire a Controller — Possible Solution
====================================================================

# Step 1: generate the controller
php artisan make:controller AuthorController
# Controller created successfully.
# app/Http/Controllers/AuthorController.php

// app/Http/Controllers/AuthorController.php

namespace App\Http\Controllers;

class AuthorController extends Controller
{
    public function index()
    {
        return 'All authors';
    }
}

// routes/web.php — the step that's easy to forget

use App\Http\Controllers\AuthorController;

Route::get('/authors', [AuthorController::class, 'index'])->name('authors.index');

WHY THIS WORKS
--------------
- php artisan make:controller AuthorController only creates the PHP
  class file at app/Http/Controllers/AuthorController.php — Laravel's
  autoloading means the class itself is immediately usable anywhere in
  the codebase, but nothing in routes/web.php points a URL at it yet.
- The `use App\Http\Controllers\AuthorController;` import at the top of
  routes/web.php is required so the file can reference AuthorController
  by its short name rather than writing out the fully-qualified
  App\Http\Controllers\AuthorController::class every time.
- Route::get('/authors', [AuthorController::class, 'index']) is the
  array-callable syntax Laravel uses to point a route at a specific
  controller method — [ControllerClass::class, 'methodName'] — visiting
  /authors now actually reaches AuthorController's index() method,
  closing the gap the chapter's gotcha warns about.
