Added a couple more minor suggestions.
"a" user vs. "the" user started to bother me but that's something we could maybe talk about/think about more so feel free to apply related suggestions or not as you think best. (I don't think we are consistent elsewhere.)
@dchyun @hashicorp/hds-engineering Since in the guidelines we say that the Stepper Nav should always be used together with navigation Buttons, I think it would be useful/helpful to include at least one example in the Code tab that includes Buttons for navigation. Would like to know what others think though.

@KristinLBradley I'd prefer to keep the existing code docs examples as limited as possible and just show the Hds::Stepper::Nav, but we could add a new section called "Composition with other components" and mirror what is talked about in the guidelines. Would that work?

@dchyun That's fair, thanks.

I think it could be helpful to add another section but I don't think it's a blocker.

Looks good, just seems like the branch needs to get back in sync with the component branch to clean up the git history/files changed.
