I'm having a ton of fun with this. But I discovered a minor pain point and I wanna make sure no one else has this same problem in the future. Potential spoilers below the fold: if you have deployed a "proxy" then you're good to look, but I will still be vague to try to avoid spoilers!

While deploying a proxy, you may encounter something that looks like this:

If you look, you'll see these sorta faint purple lines on the edge of the rectangular bit? That's the bug. They only seem to show up if you're using Firefox. If you're using Chrome, or Edge, or the chrome-alternative-that's-actually-just-still-chrome du jour, then those lines aren't there.

So basically, this part right here, in red? That part is actually totally safe. You can stand there, it's fine!
