Create a highly photorealistic high-resolution full-body mirror selfie of a {{subject}} in a modern indoor gym using the uploaded reference image with strict identity lock enabled. Her face must be 100% identical to the reference image with absolute preservation of identity. Do not alter facial structure, proportions, bone shape, skin texture, skin tone, eye shape, nose, lips, expression mechanics, age, or any fine facial details. No beauty retouching, no face refinement, no identity blending, and no stylization. The face must be an exact, unmodified match to the reference.
