At the core, we generate pure HTML and CSS, then serialize those into React and Tailwind. It would be one less step to expose the HTML and CSS instead. I wanted a narrow scope to this so that's the focus but I imagine there's a plugin setup we can do to swap in what framework (or non-framework) you would need.
