Foundations
Overview

Foundations Overview

Foundations define the visual and structural system that every component relies on. Start here before customizing themes or building new components.

What’s Included

  • Color — semantic palettes, contrast, and status colors.
  • Typography — font scale, hierarchy, and readability rules.
  • Spacing — the 4px rhythm and layout density.
  • Grid — breakpoints and responsive layout rules.
  • Icons — baseline icon set and usage guidance.

Design Tokens

All foundations are backed by design tokens in @gtcx/tokens. Tokens are the only supported path to customization.
