I'm not sure what to make of `Number("20")` in the source code. I would think it's some way to get around some filter intended to discourage CPU-intensive looping, but I don't think user scripts have any form of automated moderation, and if that were the case it doesn't make sense that they would allow a `for` loop in the first place.
Of course it's very possible someone wrote it with AI help. But almost no chance it was designed by AI.
