The user @andrisgombos is working on a new Wikimini.org skin. This user deserves access to the skin to start working on!
At the moment, this skin is not public and is not accessible.
Proposed solution:
Publish the Wikimini.org main skin on Wikimedia GitLab.
Hi @andrisgombos! I published the Wikimini skin repository on Wikimedia GitLab! Feel free to clone and hack!

Feel free to do any improvement. Tomorrow I will try to do a small cleanup and fix some things, so you can start in a better environment.
