/* ============================================================
   WINGS/CORE/RECALL.CSS — the wings' practice screen
   ------------------------------------------------------------
   One card at a time, centred, with nothing else competing for attention.
   The attempt screens are dense because you are working in them; this is the
   opposite job — you are trying to remember something, and every extra
   control on screen is something to look at instead of thinking.

   The wing's own colour comes in through --wing-accent, set on .wr-shell, so
   a Diary session and a Roadmap session are visibly different places.
