How to remove Tailwind from Docker & Laravel9 with Breeze

Question

I was just curious about removing Tailwind from Docker & Laravel (9.38.0) with Breeze installed as follows:

$ curl -s "https://laravel.build/test" | bash  
$ cd test/  
$ composer require laravel/breeze --dev  
$ php artisan breeze:install  
$ php artisan migrate  
$ composer install  
$ npm install

I remove tailwind and alpine from resources/css/App.css and resources/js/App.js and sail up, however they were there as if nothing happened... How are they included?

Additionally, I tested to install without Docker as below. Tailwind and Alpine.js were not included as I expected.

$ composer create-project laravel/laravel test2  
$ cd test2/  
$ composer require laravel/breeze --dev  
$ php artisan breeze:install  
$ php artisan migrate  
$ composer install  
$ npm install

What cause the difference?

Thanks.
