Atlas Design System

The problem

Four products, four button components, and accessibility fixes that had to be made four times. Every new feature started with a debate about which version of a pattern to copy.

Approach

Rather than pause roadmap work for a rewrite, we shipped the system alongside it: tokens first, then the ten most-used components, each adopted product by product behind a thin compatibility layer.

Every component shipped with keyboard, screen-reader and contrast checks baked into its Storybook stories, so accessibility was the default rather than a review step.
