Une invite très structurée, basée sur JSON, conçue pour Gemini 3.0 Nano Banana Pro, axée sur la génération d'un portrait haute fidélité. Elle spécifie des niveaux de détail extrêmes (détail de la peau au niveau des pores, cohérence biologique absolue), une physique vestimentaire complexe (tricot transparent avec des paillettes cristallines), une pose spécifique (tête tournée par-dessus l'épaule) et des paramètres de rendu environnementaux et optiques détaillés (objectif fixe 85 mm, ouverture f/2.8, éclairage nuageux).
