An on/off switch sized for a console row on Base UI's Switch (role switch, aria-checked, a hidden form input, Space and Enter toggle it): a control-height hit area around a 28 by 16px track, outlined and muted when off, filled with the accent when on, with no true/false text. focusableWhenDisabled keeps a refused switch in the tab order with aria-disabled. Colours from its own hoisted stylesheet, motion only under prefers-reduced-motion: no-preference.
