We've encountered some specificity issues on bedrock as we overrode existing Protocol styles to apply the rebrand styles. Making these changes upstream should allow us to removed a lot of workaround or rebuilt code:

• https://github.com/mozilla/bedrock/blob/main/media/css/m24/components/navigation-refresh.scss#L360
• https://github.com/mozilla/bedrock/pull/16078/files#diff-a3acc966d642d1704d21597a1427686bfee52ae31c611feaa68ea3932ee78ea9R96

Updating links and buttons together seems useful as they are sometimes styled by class instead of element.

mozilla/bedrock#15925 (might not be rebrand-related but good chance to fix generally related issue)
