Fusion d'intérieur Photo-Ligne : Dégradé réaliste à croquis

Transform the input photo into a complete image with a left-right fade contrast: one side maintains high-fidelity original photography with realistic materials, while the other side gradually degrades into extremely fine black hand-drawn line art along the same perspective, same object positions, and same light direction - furniture, architecture, plants, and objects retain only structural outlines with minimal cross-hatching; the gradient transition naturally passes through objects without hard cuts, and does not duplicate a second scene. The background uses a warm off-white paper surface with a minimal amount of original photo color blocks, adding one handwritten observation, without extra decorations, corner marks, or fake text.
