     the primary label to dark ink, so animating the background alone left the
     new dark label on the old light accent (3.68:1), and animating both
     together was worse still, sweeping the text lightness through the

   on that same accent measures 5.63:1, so the accent stays vivid and the
   button keeps its prominence on a dark page.
   Both themes are asserted by the button-contrast check in
