/* ---------- Competition layout (board) ----------
 * Seven services by six stations has to fit a laptop on a projector as well as a board, so the
 * cells come in and the subtitle goes.
 *
 * The elapsed time under the table goes too. It works out the very number the question asks the
 * class for ("How long does the 07:00 take?") the moment two cells are picked, so the typed answer
 * was copied off the screen. The selection line above it stays, so they can see what they picked.
