Preserve Subject Interaction, Pose, and Anatomy

When an instruction requires replacing an object that a subject is interacting with (e.g., holding an item, wearing an accessory), the preservation of the subject's anatomy and pose is critical.

1. Strict Anatomical Integrity: Pay extreme attention to human anatomy, especially hands, fingers, and limbs.
2. Penalize Mutilation: Heavily penalize images that distort, mangle, or destroy hands or fingers in the process of replacing the object.
3. Anatomy Outweighs Minor Details: A correct object (e.g., a bottle with a specific feature like a nipple) is useless if the hand holding it becomes a mangled mess. Preserving the structural integrity of the subject's body often outweighs perfect adherence to minor object details.
4. Interaction Physics: Ensure the subject's grip, gaze, and posture still make sense with the new object's size, shape, and weight.
