+Oliver, straight after the draw screen went: "warum sollten wir noch mischen? wäre es nicht gut
+von leicht nach schwer zu spielen?" — right again. Without the screen the shuffle was invisible
+novelty, and a bad roll paired the strongest challenger with the one-game round one, INVERTING

+`cupRoundsFor` is deterministic now: one band position per round, ascending, the final the top —

+collapsed to a read; `cup.draw`/`cup.played` are gone (startMatch keeps the dead `draw` parameter
