Candid Social Media Selfie Prompt (Escalator)

A detailed JSON prompt for generating a candid, high-angle iPhone selfie with a social media influencer aesthetic. The subject, a young woman with short wavy hair, is on an escalator in a shopping mall, making a playful duck face/kiss pout expression. The prompt specifies natural indoor lighting, a cream beige tank top, and details like a black leather shoulder bag strap and a hair scrunchie on the wrist.
