“People sit at the core of our design system and shape what good looks like: distinctive yet familiar, with a flair of style that makes it easy to come back to every day.”
Paper first
Every surface, a texture you can almost feel with a typeset that has an unhurried editorial rhythm.

A gentle settle
Hovers lift, presses set down. Nothing bounces, nothing loops, nothing hurries you along.
Begin with a single command.
Add the Quill theme with the shadcn CLI, import from the registry, and compose. The Storybook holds a story for every component, every state, both themes.
