+- **composer.json requires laravel/framework, not illuminate/* components:** the package uses `Illuminate\Foundation` (AboutCommand, PendingDispatch, the `config()`/`app()`/`event()`/`dispatch()` helpers), which only ships inside the framework. The CI matrix pins `laravel/framework` per Laravel version; `tests/Unit/ComposerManifestTest.php` guards the requirement.
