Build me a simple open source rich text editor for the web that feels ready to use right away.

I want a clean editor with the usual text formatting tools like bold, italic, lists, links, quotes, images, and headings, and it should be easy to drop into a plain JavaScript app or a Vue or React project. Please make the editing experience smooth and modern, with a toolbar that is easy to understand and content that can be edited and saved as HTML.

It should come with a working demo page and clear docs so I can see how to use it quickly. If there are any tricky details or current best practices for rich text editing, look up the latest docs online if you need to.

Keep it polished, simple to configure, and ready for real world use.
