/* IconCaptcha, dressed as one of our form rows.

   The library ships a single hard-coded look — 330px wide box, blue accent, uppercase
   titles, 8px radius — that reads as a foreign widget dropped into the registration
   forms. It exposes no custom properties, so the only way to reskin it is to re-declare
   its own selectors. That works because app.js imports this file after the library
   stylesheet: the rules below have the same specificity and win on order alone. Keep
   that import order.

   Only the frame and the palette are ours. The icons themselves come from a PNG the
   server renders, and the geometry of the challenge strip (the 320px icons/selection
   area) is load-bearing: the click coordinates are mapped back to an icon using the
   element width, so resizing it would break the selection. */
