CRITICAL COMMAND: Perform a direct, 1-to-1 face replacement.
BASE IMAGE: Use the first image (the girl in the Hogwarts-style scene) for the body, clothing, background, and overall atmosphere.
FACE SOURCE IMAGE: Use the second image (the user's latest upload of the girl's face) for the face ONLY.
INSTRUCTION: Replace the face in the BASE IMAGE with the face from the FACE SOURCE IMAGE. This must be an exact, literal transfer. Do not interpret or change the facial features. The goal is a perfect, seamless photo-merge, as if you cut out the face from the source and perfectly blended it onto the base image, matching the lighting and color grade.
