# The soot field's bend lane (the FIRE_FIXTURE driver): a 4 m/s wind
# (FROM 25, the manual default direction) takes the plume - but the
# flame envelope's sheltering stands the column up over the fire first
# (the 2026-08-18 eyeball: "right over the fire I would expect it to go
# upwards before going mostly horizontal"). The aloft mass drifts
# downwind hard while the column directly above the brazier keeps its
# mass. Ends before the downwind orb ignites.
# weather: wind 4 25
