Draws the standard focus ring on the indicator of a control whose real input is visually hidden; a checkbox or radio focuses an opacity-0 input, so the ring has to appear on the picture beside it. The ring is painted imperatively on the indicator's own element, which is the only element whose border-radius can shape it, and only on :focus-visible, so pointer clicks stay quiet. Owning it here means a theme-supplied indicator cannot ship a control with no visible focus (WCAG 2.4.7) by ignoring a prop.
