Video systems must maintain relationships across time. This authored teaching simulation changes how many earlier drawings its code uses as references; it does not measure a real model's memory or guarantee that wider context locks motion together.

Set how many earlier authored frames this browser simulation uses when drawing the current one.
Past frames ghost behind the current one, like an animator's light-box.
In this designed animation, a short span adds more variation and a longer span adds less. That result is built into the code.
Predict what the simulation will display when it uses only one earlier frame.
Change only the simulation's reference span; keep playing.
How do the onion-skin ghosts line up at each setting?
Name what changed in the simulation, then separate that observation from a claim about a real architecture.
