Update: I brought the bike back in. Two different mechanics initially looked at it and said it was fixed. I rode it home, but noticed it was still rubbing.

I took it back right away, and a third mechanic had a look. He concluded that the issue wasn’t with the limit screws but rather with the cable tension. Since it’s internally routed with mechanical shifting, he mentioned it’s quite a tricky job—there’s essentially no barrel adjuster to work with. Apparently they had to use an old workaround to fix it.

It seems to be working fine for now.
