  /* A FIRST-RUN GATE, so it outranks decoration for the same reason the consent
     gate does. At 10000 the invite arrival ticket (10050) painted over it and
     swallowed the clicks on Save — an invited player could not choose a
     username. Kept just below the consent gate, which is answered first.
