OP is misrepresenting it, because its not just mac catalyst, its really everything. I don't understand the full scope, but there is definitely a browser renderer being used for text. See this[0], which I encountered only after days of confusion about why my text was looking suspiciously[1] like the default browser stylesheet

I don’t know what he’s talking about. Catalyst is actually pretty complex, and is indeed native — it seeks to bridge the API differences between uikit and appkit — it’s not the macOS equivalent of electron using webtech.

Catalyst apps are native, yes.
