 * Six cards, tilted, and each one a little differently.
 *
 * A stack of identical rectangles reads as a form to be endured. Nudging each
 * card off true - never more than a degree or so - makes the set read as
 * something laid out by hand rather than generated, and the eye follows a row
 * of things that are not quite aligned further down a page than a row of things
 * that are. They straighten on hover, so the one being read is the one sitting
 * level.
 *
 * Three across, two down. The sixth card is not a step - it answers the
 * question everyone asks next - so it carries a question mark rather than a
 * number and a warmer border, and stays in the grid instead of hanging off the
 * bottom as an aside nobody reads.
