Lithos UI is now an npm package

Lithos UI is a free, open-source React component library built on a genuinely original architecture, not a fork of an existing design system.

What makes it different:

Zero-Gap layout system — no CSS `gap` property, ever

Automated contrast engine — readable text against any accent color, computed live

Physics tokens — consistent interaction behavior across every component

🧩 16 components + 10 full page-section templates

The real differentiator: you choose how to use it. `npm install` it like any library, or copy-paste the raw source into your own project for full code ownership. Both paths are first-class, documented side by side on every component.

100% free. No paid tier, now or ever.

Looking for contributors, real-world users, and sponsors to help keep it sustainable long-term.
