/* The past handoffs page ends on a still beach: two sets of footprints walking side by side along the water's edge, the last
   few taken by a wave. It is a picture only, with no caption and no motion. It sits at the bottom of the page, and at the
   bottom of the screen when the list is short. It keeps its own proportions, so the whole walk shows; on a narrow screen it
   crops from the left, so the wave stays in view. The top fades into the page. */
