Button

A polymorphic button built on Base UI's useRender. Ships 8 visual variants (default, secondary, outline, ghost, link, destructive, destructive-outline) and a full set of sizes including icon sizes (xs–xl). Has a built-in loading state that overlays an inline spinner and hides the label, a render prop for rendering as any element or as a child, and focus-visible / pressed styling out of the box.
