Permission to use Catppuccin theme as reference for a tutorial

I'm writing an article on [CivitAI](https://civitai.com) on how to create a Stable Diffusion UI theme. I figured this would probably be a given but I wanted to ask anyway; can I use the Catppuccin .css file as a reference tool for people to look at? The personal theme I created uses it as a base and I wanted to add screenshots of the code to give the users something to base their work off of. I have provided a link to the Catppuccin repository and credited the team.
Here's an example of the contents:


Read the referenced Catppuccin repository and the .css file the author wants to show in the CivitAI tutorial. Review the request, attribution, and screenshots, then record whether permission is granted or declined; done means the maintainers have made and communicated that decision.
