after npm run prod there aren’t much styles

[ajuchacko]

#I followed the documentation and created a new project with laravel/breeze package

curl -s “https://laravel.build/example-app” | bash
cd example-app
./vendor/bin/sail up
sail composer require laravel/breeze --dev
sail artisan breeze:install react
sail artisan migrate
sail npm install
sail npm run dev

Everything looks and works good upto this point but if I run ’npm run prod’ then the styles are not taking effect?
Why would that be? I could not find any more info on the doc.
