The prompt

Change the yellow jacket in the red circle to a dark green waxed jacket, and change the black plastic crate in the green circle to a wooden one. Do not render the circles in the output.

Notes

The jacket changed 22 times more than the red coat a few steps away. The circle bounds the edit; it does not stop the rest of the frame being redrawn.
