/* Keyboard focus visibility — applies to every interactive element by
   default so tabbing through the site always shows where you are, even
   on custom controls (buttons, tabs, filter pills, etc.) that don't get
   a focus ring for free. Scoped to :focus-visible so it only shows for
   keyboard/assistive-tech navigation, not mouse clicks, and sits above
   any individual component's own :focus-within styling rather than
   fighting it. Components that already remove outline (e.g. inputs
   inside a bordered search box) still pick this up since outline is
   drawn outside the box model, not clipped by the component's own
   border or background. */
