# Light governor stagger: the run boots at game hour 6 (sunrise, sun
# below the 12-degree want-on threshold), so the day/night-driven
# sources (8 gas lamps + the fire + the mirror = 10) queue and drain
# ONE per sim tick - before the governor every cluster registered the
# same frame gas crossed 0. The sun crosses the threshold around frame
# 411 (hour 7.37) and every source drops at once (turning off is never
# queued). F3 at frame 500 forces night: the queue refills and drains
# 1/tick again.
