Could OP or someone else give an overview of how web-based interfaces work on native apps like this, without using something like electron? Is there a full js interpreter, dom, css parser, etc in something like Foliate?

In the readme I see:

   The following are runtime requirements:
   gjs (>= 1.52)
   webkit2gtk

So my guess is that it's just using webkit for the html rendering.
