/* ==========================================================================
   Tune-the-string check (.ggc)
   A small drag-or-arrow puzzle the four public forms ask for before they
   will send. Markup is built by assets/gogo/captcha.js.

   The widget sets its own colours from the data-tone that captcha.js works
   out from the background behind it. Inheriting currentColor was the first
   attempt and it was wrong: the newsletter form in the footer inherits dark
   text even though it sits on brand blue, so the label came out near-black
   on blue and the target was invisible.
