/* ============================================================
   Korbel.ai — Component state layer
   Real CSS states for interactive components: hover, active,
   keyboard focus (:focus-visible) and disabled. Replaces the old
   JS mouse-handler styling, which was invisible to keyboards.
   Press shrinks ~1% — steel doesn't wobble. Focus is the same
   3px steel halo the inputs use; never a coloured ring.
