docs-bug(COMPONENT): What does it mean when system token is `None` in overrides (styling tab)

Documentation Feedback

It is a bit ambiguouns when None is mentioned for system token, I cannot find any documentation explaining what None means, does it mean its not used, being developed or I need to style it myself, can this be documented?

@kai1992cool None means that the default value of the component token is a plain CSS value (e.g. 16px) and is not referencing a system token. It doesn't mean the token is unused or in development, it just indicates that there's no mapping to a system-level token.

I think we can come up with a better label for this case or at least a tooltip to explain what it means.
