The target hull now lies along the groove axis (yaw derived from the
groove constants), set back 22 m from the groove end so both hull ends
rest on the flat groove floor. The mooring, spawn and first route
waypoints move to z = -210 and the decoy yacht to (-30, -150) so no
wreck is farther than 320 m from the mooring and no two wrecks are
farther than 260 m apart (spec 4.1). The spawn faces south toward the
site. Four contract assertions pin the budget, the spawn heading and
the hull orientation.
