/* ============================================
   Colour on the full grid

   The k- tints already existed but only reached .pi, which the small
   cards do not use — they use .ai. So a card in the full grid picked up
   the gradient background and then rendered a grey icon and a grey link
   on top of it. Extending the same rules to .ai finishes the job.
