  "prompt": "Use case: identity-preserve.\nAsset type: finished architectural 3D visualization for an art studio gallery.\nInput image 1 is the exact edit target: the selected B version of \"The artist's corner\". Images 2 and 3 are identity references of Margherita, especially the seated side profile in image 3.\nPrimary request: refine ONLY Margherita's face and glasses in image 1. The current face feels strange; create a new B revision with a convincing, naturally proportioned stylized likeness of the woman in the photographs. Match her distinctive gentle nose profile, soft rounded jaw/chin, cheek volume, realistic eye size and eyelids behind thin round wire glasses, subtle relaxed closed-mouth expression. She is calmly concentrating on her painting, eyes directed toward the canvas. Maintain a coherent side/three-quarter profile, believable eye placement and clean glasses geometry. Keep the original head angle, head size and warm lighting. Give her face the same softly rendered 3D material/style as the surrounding scene, never a pasted photographic face.\nInvariants: preserve framing, camera, room geometry, brick walls, concrete structural frame and floor, windows, sunlit shadows, easel, every painting, paint trolley and all tools. Preserve her long loose dark-rooted blonde waves, body proportions, clothing, tattoos and painting pose. Her anatomical RIGHT arm extends toward the canvas and paints with the brush; her anatomical LEFT tattooed arm holds the palette near her waist. Do not reverse hands or arms. Keep this exact arrangement unchanged.\nChange only the face/glasses region and its tiny necessary transition into adjacent hair. No new people, objects, lettering or watermark. Output one full image at the same landscape 3:2 framing as image 1."
