Design System

A design system is a structured set of reusable design decisions.

It can include colors, typography, spacing, grids, components, states, variants, interaction rules, documentation, and usage guidelines.

Why It Matters

  • keeps interfaces consistent
  • helps teams scale design
  • reduces repeated decisions
  • improves developer handoff
  • makes product evolution easier

In UID 07
