/* The CMS Elevate theme colours every anchor with

   specificity, so the theme's rule is (0,1,1) — stronger than a bare button
   class at (0,1,0) — and its link blue was winning over the button ink,
   printing blue text on the magenta fill at about 1.3:1 contrast. Scoping to
   the section root outranks it, and naming the states explicitly covers the
