# Joint (W, U) safe region: co-sweep the uncle window W and the uncle cap U at the transition
# delays found earlier (U=1 is W-limited at delay ~8 and U-limited at delay >=16). Shows where
# "widen the window" stops helping and "add an uncle" takes over. Blend mixnet, geographic
# transport (geo), hops=3. Latency is in SLOTS (1 slot = 1 s).
