# 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 mirror = 9; the rig fire left the demo
# with the voxel-fire rewrite) 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.
# frames: 600
