  .step is a flex column, and margin-top:auto on the box absorbs all free
  space ABOVE it, pinning the box to the column's shared bottom edge. Fixed
  box height means equal bottoms imply equal tops. A 2- vs 3-line description
  can never move a box out of alignment, at any viewport >= 880px, because the
  box position derives from the shared column height, never from its own text.
