Detailed JSON Prompt for Canon IXUS Aesthetic Portrait

A structured JSON prompt for Gemini Nano Banana Pro, aiming to generate a hyper-realistic portrait with a Canon IXUS point-and-shoot aesthetic. It specifies detailed subject constraints (matching a reference image exactly, no face edits), hair, makeup, expression (cute, naive, slightly sexy), pose (flicking hair), clothing (strapless top, low-waisted jeans), and environment (modern pub setting with specific foreground props).
