 * Cards here are borderless: structure is carried by spacing and by fill,

 * between cards is what separates them, and rows inside a card are told
 * apart by the gap between them rather than a rule. Colour carries meaning:
 * the ground is neutral, cards are paper, and the brand lime appears only on
 * the call to action, the headline underline, and small markers. Nothing
 * casts a shadow and nothing is boxed in.
