/* Visible keyboard focus. This selector fires on keyboard navigation only, so a
   mouse click still gets no ring. outline-offset is load-bearing, not cosmetic:
   white on --accent measures 1.65:1, but the 2px offset lifts the ring off a
   filled button onto the page background, where it measures ~19.6:1. Never
   switch the outline off to defeat this - fix the rule that needs it instead. */
