Design system
The code-connected toolkit – tokens, components, patterns, rules – built from brand guidelines to construct consistent product UI at scale.
A coded, governed toolkit that lets a product look and behave consistently at scale: tokens at the bottom (the decisions), components in the middle (the building blocks, each with its variants and states), patterns on top (the solved problems). It’s the “how to build it” layer underneath a brand’s “what it should look like” layer – see brand guidelines for the boundary.
What separates a system from a pile of components is the relationships: pieces reference and nest into each other (composability), so a change at the bottom propagates everywhere above it, and someone decides who may change what (governance). Quality is not component count – a system with 30 trusted, documented components beats one with 200 that teams quietly route around. The honest measures are whether product teams voluntarily rely on it under pressure, and whether it says clearly what it doesn’t cover yet. This site’s own system is live at /system – every swatch on that page renders from the real tokens.
