It exposes status and log semantics, with aria-label, aria-live, aria-pressed and aria-hidden kept in step with state. Changes that matter are announced through a live region.

No custom key handling; Tab and the native activation keys do the work.

Motion #

It declares no animation in its component source. Any transition comes from its stylesheet, which uses the duration tokens that collapse to instant under prefers-reduced-motion.
