I've been working on using Svelte + Rust to make desktop apps with native UI frameworks [1], resuscitating a COVID era side project that I felt was intractable at the time. I havent updated the docs or README.md so you'll have to point an agent at it to figure it out, but so far GTK/QT are fairly complete and I'm working on WinUI/AppKit.
