The mystery machine keeps its mood to itself

"Random" read as random ACTIONS, and a revealed random pick is barely
a mystery anyway. The fourth workshop button is now "mystery": the
server rolls the temperament and keeps it — the join line records it
for replay, the drive loop plays it, but the room tells the table
only "mystery". Roster and scoresheet show ⚙ mystery; the machine's
behavior is the only tell.
