     <div class="card green">            green ground, green rule
     <div class="card blue rule-green">  blue ground, green rule
     <div class="card orange soft">      the lighter ground
     <div class="card orange side">      the rule down the left: a callout
     <div class="card tight">            less padding; roomy for more

   A tint sets two variables, which default to blue and which the regions
   below and a site's own classes (the COE thrusts, .t1 … .t5) may set too:
   --tint, the ground as an RGB triple, and --rule, the colour of the rule.
