Aurora

Aurora started as a rescue job. Four product teams had drifted into four different button components, three spacing scales and a colour palette nobody could name. The first six weeks were pure archaeology — auditing every screen in production and mapping what was genuinely different from what had simply been rebuilt twice.

What shipped is a design-token pipeline that publishes one source of truth to Figma variables and to a typed React package in the same step. Adoption was the hard part, not the code: the system only stuck once the migration path was a codemod rather than a deprecation notice. Twelve teams now build on it, and a palette change lands everywhere in one release.
