Hyper-realistic Gym Portrait of a Shy Girl

A highly structured JSON prompt for Nano Banana Pro to generate a hyper-realistic, cinematic portrait of a fictional fitness model in a gym setting. The prompt specifies detailed wardrobe (grey sports bra, ribbed brown shorts), pose (sitting on a fitness chair, V sign), lighting (cinematic, high contrast), and texture details (realistic skin and fabric), while explicitly constraining the output to avoid real person identity matching.
