/* Text columns ---------------------------------------------------------
   Boxes of text two across, half and half: an optional icon, a heading, the
   markdown text and an optional button at the foot. One column on a phone,
   two from the tablet up; a third box starts the next row. The boxes of a row
   stretch to one height and the button sits on the box's floor, so two
   buttons in a row line up whatever the texts above them are. */
