Granular Gym Mirror Selfie Prompt

A highly granular, structured JSON prompt for Nano Banana Pro detailing a gym mirror selfie. It specifies technical settings (8K, 4:5 aspect ratio), strict face preservation, and minute details of the subject's pose (squatting low, holding phone), wardrobe (off-yellow sports bra, white leggings), and the gym environment, designed for high-fidelity image generation.
