This is now done and deployed in production! Thanks to everyone involved. Special thanks to Tyler and Chad for their help with the rather unexpectedly messy deployment.

https://phabricator.wikimedia.org/T171000

The resulting repos can be seen here:
https://github.com/wikimedia/mediawiki-skins-MinervaNeue
https://github.com/wikimedia/mediawiki-extensions-MobileFrontend

The next step would be to break the MobileFrontend dependency on the Minerva skin. I've setup an epic https://phabricator.wikimedia.org/T171000 (subtasks to be filed as I find them) and would appreciate help doing this if anyone is looking for a fun side project and interested in improving our skin ecosystem!

There is a milestone on the MinervaNeue project tracking all open bugs:
https://phabricator.wikimedia.org/project/board/2799/

Your help is welcomed and appreciated!!
