+// moment, including while the tick-driven logout countdown (owner goroutine)
+// transitions the session to the character menu. The dispatch read
+// sess.State as a plain field, which the race detector flagged; the state is
+// now an atomic on net.Session. This test drives both sides concurrently and
+// must run clean under -race.
