What are you trying to accomplish?
Safely test rem units for all margin base and utility styles behind a feature flag. Each change is using a CSS var that only exists behind a feature flag, with a fallback to the current value (scss var). There should be no visual changes to margin styles with this change.
What approach did you choose and why?
CSS vars with fallbacks as this has been a useful method for testing our new set of design tokens.
What should reviewers focus on?
