  1. Basic object edits (fast wins)

Change the yellow car to red. Keep everything else identical.

•	Replace an object:

Replace the vase on the table with a small potted fern. Keep table, lighting, and background unchanged.

  1. Controlled edits (preserve style + composition)
•	Change time of day but keep style:

Change the scene to daytime while maintaining the painting's original brushwork and color palette. Keep composition and object placements unchanged.

•	Background swap while locking subject placement:

Change the background to a beach while keeping the person in the exact same position, scale, pose, camera angle, and framing.
