Thanks for the PR! I'll try to review it this week.

Actually I'm considering a different path for MistCSS (need to prototype a little before) and the code for renderers may become obsolete.

I can merge the PR anyway if you need it or you can use your fork, let me know what you prefer.

I am very much looking forward to it.

Please merge this PR 🙏

I had done some other refactoring and enhancements, but it might be better to manage them in a forked repository.
I have no plans to release it as an NPM package at this time...
