Not "everyone moves once per turn": each actor has a speed, and an action costs time
scaled by it. A hasted creature gets two moves to your one, a heavy weapon costs more
than a dagger, and a slowed one loses turns, all of which fall out of one number rather
than needing special cases.
The queue is ordered by the time at which each actor next acts. now only ever moves
forward, so effects that expire can be timestamped against it.
