Modern Loft Staircase Portrait Identity Preservation Prompt

A highly specific prompt for Nano Banana Pro requiring strict identity preservation of a woman from a reference photo. The goal is to place her in a new scene: sitting on a raw concrete staircase in a modern loft, wearing a cream oversized knit sweater and dark jeans, with soft natural daylight. The prompt includes detailed negative constraints to prevent style deviation and ensure ultra-photorealistic quality.
