Design Systems at Scale

A design system at scale is infrastructure — tokens, governance, visual regression, and measurable adoption across product teams.

This module covers three-tier design tokens, centralized vs federated governance, semver with codemods, Chromatic visual regression, accessibility CI, adoption dashboards, and the RFC workflow for federated contributions.

Staff interviews ask how you ship breaking component API changes to 50 teams without a big-bang migration — semver, codemods, and N/N-1 support are the answer.

Pairs with Frontend Platform (Module 17) and Staff Frontend System Design (Module 16).
