From my original comment, "cross-platform UI toolkit that is easy to use, has all the accessibility features of the browser built in, and has a UI control toolkit as rich as say mui.com ... Support SVG as well as stylized layout similar to html+css"

So, you've failed to meet the requirements from the start.

I've also said, many times now, that you can use browser tech without an entire browser and the answer doesn't need to be electron.
