Introduction
A modern, borderless React UI kit you can own. Solid surfaces, top-lit curves, accessible behavior and an accent that changes at runtime.
The idea
Most component libraries give you a fixed visual language or a pile of unstyled primitives. This kit sits in between: behavior and accessibility come from Base UI, while the visual language is owned here — semantic tokens, solid fills, a top-lit curved edge and a restrained motion system.
There are no gray outlined boxes. Depth comes from tonal surfaces, a light rim on the top edge and a barely-there vertical gradient. The accent is generated from one color, so the whole system re-tones without hand-editing every variable.
Three ideas
Borderless
Solid fills and edge light instead of outlines.
Expressive
Pill shapes, sliding tabs and a vibrant accent.
Owned
Semantic CSS variables, no hidden brand paints.
Quick start
Install the package, import the stylesheet once, and scope your app with data-ui="kit".
Put data-ui="kit" on <html> when you use portalled overlays, so dialogs, sheets and popovers inherit the tokens.
