9-Grid K-Pop Idol Photocard Style Prompt (JSON)

A JSON prompt for generating a 3x3 contact sheet (9-grid) of a single person (specifically a young Asian woman) in the style of a K-pop idol photocard. It requires a reference image and a high strength setting (0.8-0.9) to maintain identity consistency while varying facial expressions and camera angles across the nine panels, with optional festive accents.
