Analog flash photography portrait prompt with identity lock

A highly specific JSON prompt for generating an analog-inspired digital portrait of a young woman. It enforces a strict identity lock (100% facial accuracy), specifies a 'joyful, playful' expression, and mandates vintage film flash photography lighting with strong, soft highlights and authentic flash contrast against a minimalist white wall background.
