First of all this is a great effort to integrate tailwindcss with Drupal thank you. The main.css file gets more than 620KB unzipped and I suspect it will be mostly unused selectors I have used https://github.com/spatie/laravel-mix-purgecss and I have created a minimal patch for it which I am attaching just for discussion. It works and it can reduce the file size down to only the used selectors. Would you consider it ? Right now I have it running with npm run build but it should be run only before pushing to production
