Ride: roadside actor figures among the props on some songs

Browse Source 
Two seeded slots on ~40% of builds hold figures of the track's own cast, grown on first update like the crew (identity arrives via update), normalized to person-scale with feet planted via measured bounds, palette-recolored per frame, glancing around analytically. Static for the whole video: they stream with their slots and never pop. Verified variance across seeds, pose and planting.
