While it does make sense to use "rem" in Orbit components CSS codebase, I am not sure about using rem for documentation stories and event Chromatic stories as most people tend to think in term of pixels.

Great point. For the chromatic stories I was planning for the eventuality of testing rems in Chromatic too. It could be px too. As for documentation the idea is to support the users who change their font size even in documentation.
