# The soot field's direction lane (the FIRE_FIXTURE driver): 4 m/s FROM
# 205 (TO ~ opposite the default lane's). The column shape mirrors
# soot-wind; the drift reads positive along this wind's axis. Ends
# before the fixture orb downwind of THIS direction ignites (the
# default upwind orb, same ~1611 timeline by symmetry).
# weather: wind 4 205
