Structured JSON Prompt for Low-Key Cinematic Rock Climber Photo

A highly detailed JSON prompt for Nano Banana Pro to generate a realistic cinematic photo of a female rock climber in a gym, seen from behind while holding cable handles. The prompt meticulously specifies the subject's physique (lean athletic, defined upper-back muscles), clothing details (ultra-thin string-strap sports bra forming an X-shape), low-key lighting, and photography style (shallow depth of field, cool highlights on muscles).
