Fusão Interior Photo-Line: Gradiente do Realista ao Esboço

Transform the input photo into a complete image with a left-right fading contrast: one side keeps high-fidelity original photography with real materials, while the other side gradually degrades into ultra-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 a few cross-hatching lines; 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 texture with very few original photo color blocks, adding one handwritten observation, without extra decorations, corner marks, or fake text.
