/* Visible keyboard focus — accessibility floor, not optional.
   Layered for browser compatibility: older Safari (<15.4) doesn't recognize
   :focus-visible, and CSS drops an entire rule when its selector is invalid —
   so a :focus-visible-only rule would leave those users with NO focus
   indicator at all, not a degraded one. The plain :focus rule below is the
   fallback those browsers actually see; :focus:not(:focus-visible) then
   removes it for mouse users on browsers that DO support :focus-visible,
   and the final rule re-applies it specifically for keyboard focus there. */
