What happened?

I'm using the "dark" skin and when I launch Jekyll to serve the website I see these:

Which in turn is a duplicate of #4054 🙃

To tag along with this:

• Susy is deprecated and will no longer receive updates. This is the grid system that mmistakes uses.

Doing the switch over to modules is relatively painless, but requires a custom github action (otherwise horrible things happen), and I'm happy to produce a PR. Based on comments in other issues, it wouldn't be integrated because of remote-theme users.

Perhaps it's time to fork and have a less-mistakes repo that expects a proper Jekyll and GitHub Action deployment, but keeps up with upstream changes?
