I was looking to try and get the Steam Deck's keyboard themes, the official ones but without getting them via the official methods. The main reason is that when getting them through the official methods they don't work offline but CSSloader themes do work offline and have no DRM.
I think they don’t worth the trouble. You are better installing Decky, getting CSS loader and installing any of the keyboards available there, they are much nicer.
In all honesty I'm mostly interested in the classic green one, I have another green theme for the whole system that matches it however it's annoying because when my deck is offline I can't use the keyboard theme.
I might also want the night shift one as well, but mostly just the green one.
