Building GTK4 Applications Like Websites

I get what the author is trying to do here and it's clever, but for me it kind of underlines that the developer experience would be much nicer if you build a 'native' gtk4 application. Web apps are hard work!

Congratulations Mr Author, you have reinvented WPF (XAML).

I actually thought Glade was deprecated? I'm surprised to see it mentioned... Or maybe I'm wrong or maybe the author didn't know!
