t4t5/sweetalert ? reverse-engineered prompt

Build me a nice replacement for the browser alert box that feels modern and polished.

I want a small JavaScript library that can show friendly popup dialogs for success, error, warning, confirmation, and simple text input. It should be easy to use with one line like swal("Hello world!"), but also support more detailed options like a title, message, icon, confirm button text, and a way to wait for the user’s choice before continuing. If the user confirms something, I want to be able to handle that with promises or async and await.

Please make it look good out of the box, with smooth styling and a clean modal centered on the page. Include a few example usages, a basic docs page, and make sure it works nicely in a normal web app. If you need to check current docs or patterns online, feel free to do that.
