/* EPC+F cards: frosted glass over the plant being built, each with its own drawing (app/epc.php).
   They rest on the desert (left and right of the plant), never over the halls whose roofs slide in.
   The default state is the finished drawing; in animated mode a card that has not arrived yet (no .is-on)
   holds the start state, so every arrival replays it. hero.js places them. */
