Fotorealistisches Gym-Selfie-Porträt mit spezifischer Komposition und Farbpalette

A highly detailed, photorealistic prompt for generating an image of a young, fit woman taking a mirror selfie in a modern gym. The prompt specifies her appearance, clothing (high-saturation rose pink sportswear), pose, the surrounding gym equipment (Smith machine, barbell plates), lighting (cool industrial light), and a strong color contrast between the pink and dark gray/black elements. It also mentions the use of a reference image of the model for identity locking.
