A design system that starts on the web rarely fits mobile directly. This post shows what still works on mobile, what doesn't, and how to keep one source of truth (one place that stores each design decision) for both.

Design tokens are the twenty percent of a design system that decides whether the other eighty holds together, and the part of them you actually have to understand fits in one careful read.
