/* Random sort - fetch mode.

   Holds the server-rendered items while the request for a fresh random
   selection is in flight, so the visitor never sees one set of items
   replaced by another. visibility (not display) keeps the box in flow, so
   nothing shifts when the swap lands. Removed by random-sort.js as soon as
   the response arrives or the hold times out. */
