Shadcn Library
Overview of the Shadcn-style prototype library built on Proto UI Base.
The Shadcn library projects a familiar, crisp, and practical product interface style over Base interaction protocols. This page is a quick index: each prototype shows only its first basic demo, without API tables or code examples.
The Shadcn catalog entities currently remain in the draft lifecycle. This page reflects the current official implementation rather than a frozen stable guarantee.
