API

variant: default / primary
disabled: boolean, default false
Activation, focus, keyboard and disabled behavior are inherited from Base Button; the visual layer owns no second interaction state.

This is a draft, private, unreleased source projection. The archived light palette stays fixed in dark hosts. The Web demo does not establish general Prototype Compiler or GPUI, Flutter, or Qt conformance. Browse the implemented subset.
