   to a single line, then to dashes, then to periods before it gives out
   altogether - and the corners fade with it rather than staying square.

   Four stacked layers, each confined to its own band down the height:

     ::before      inner line of the double, gone by a third of the way
     border-image  the main rule, thinning as it descends
     ::after       dashes, faded in and back out across the lower middle
     background    periods along the bottom edge and the tail of each side

   All four are full rectangles, so a corner carries whichever tiers are
   still alive at that height - which is what made the originals look
   like they were dissolving rather than simply stopping. */
