In-browser/serverless preview build

Hi 👋

(Disclaimer, I don't know all the details of how markdown is turned into a website, but I have an idea)

I believe there is a huge potential for content to be used in browsers as a wysiwyg-like editor. I understand that we would probably have to run a partial nuxt build in the browser - or potentially in serverless environments.

Given the tight integration of content into kit and other probably node-only layers, is there any alternative that would yield a similar result? Dev mode seems like a good candidate, but it requires a server to be running and user input to be run as code/trusted.
