/* Colors.
   Two rules govern this palette:
   1) Exactly ONE accent (moss). It means "this is what's on now". Nothing else.
   2) No semantic red for task state. Red exists only for destructive system
      actions (delete account). Overdue is never colored — it recedes.
   The primary axis is not status, it is calm: the --recede-* ramp steps content
   backwards (less contrast, less saturation) as it ages. */
