/* ==========================================================================
   B-Digital Mark blog -- article cards (listings and related posts).
   Shared by list and single views; depends on base.css tokens.

   Every card is the same rectangle: a 2:1 picture on top, shown at its own
   proportions so it stays sharp, and the text below. Cards in a row stretch
   to equal height. A post without a featured image gets a colour-orb picture.
