Hey I implemented this bug 3 years ago or something 😌 I'm proud it almost made it to 2022

Might be a good chance to update that red to use a dark-mode-compatible CSS variable from GitHub. Maybe the danger buttons have one.

Thanks! We can drop the media query for the 3-color fallback. They're only there to avoid defaulting to transparent, it's fine if they're not perfect in dark mode when missing. They'll actually be useful to show us the variables aren't working.

It's better we just have a debug mode where it automatically scans for all CSS variables and report missing ones.

This can stay I suppose

I've been thinking about setting up automated tests running on GitHub.com with a real user. But it takes a lot of effort to set up and a lot of effort to write tests. I'd rather focus on the bug fixing than writing something that just finds more bugs 😜
