Introduction
How Cal.com uses Coss UI in product.
This is the Cal.com design system docs app. It documents how we use Coss UI in Cal product — patterns and Cal-aware Product UI — not a mirror of the full Coss primitive catalog.
Primitive APIs live on coss.com/ui (Cal-owned). This app focuses on Cal-specific guidance.
