  "prompt": "Use the reference photo strictly as the identity reference. Preserve the exact person, facial structure, hairstyle, age, gender, body proportions, and likeness without changing identity or adding extra people. Transform the subject into a minimalist, hand-drawn single-line doodle illustration.\n\nIllustration Style:\nA minimalist continuous line doodle where the entire subject is drawn using one unbroken, fluid, organic line with slight natural imperfections, as if drawn without lifting the pen from the paper.\n\nLine Quality:\nSmooth yet slightly imperfect pen or pencil stroke with subtle pressure variations. Hand-drawn and human feel, avoiding mechanical vector precision.\n\nColor & Texture:\nMonochrome line art in [black, dark brown, or soft navy]. Minimal flat background with optional faint pastel watercolor wash or crayon shading behind the subject.\n\nFacial Features & Form:\nHighly simplified features formed naturally through the continuous stroke: dot or small arc eyes, simple curved smile, recognizable yet abstracted silhouette maintaining authentic likeness.\n\nShading & Lighting:\nNo photorealistic shading or 3D lighting. Form and volume are suggested solely through contour flow and negative space.\n\nBackground & Mood:\nOff-white textured paper background, calm, creative, and cozy storybook aesthetic.",
