I like the idea of using a transparent background in the webview. That would compose really well.

The primary motivation for winforms was getting easy access to OS-native multiline input controls, clipboard, audio, image handling, etc. I could have just put kestrel in the console app and served it as a pure web app, but this is a bit more clunky from a UX perspective (separate browser window, permissions, etc.).
