/* ============================================================
   ARIA guide  -  the mascot who hands a visitor to the right tool.

   People kept saying they read the four descriptions and still did not
   know which one they needed. The descriptions were not the problem: the
   mapping was, and it was being left to the reader. ARIA does it instead.

   This file styles the entry point, the overlay, the click-through
   bubbles and the tile rows. The hands-on "how to use" walkthroughs are
   a separate piece and are not built yet.
