포토-라인 인테리어 병합: 리얼리스틱에서 스케치 그라디언트로

Create a complete left-to-right fade comparison image from the input photo: one side maintains high-fidelity original photography with real materials, while the other side gradually degrades along the same perspective, same object positions, and same lighting direction into extremely fine black hand-drawn line art, with furniture, architecture, plants, and objects retaining only structural outlines with a few cross-hatching lines; the fade boundary naturally passes through objects, without hard cuts, and without duplicating a second scene. Background uses a warm off-white paper surface with very few original photo color blocks, adding one handwritten observation, without extra decorations, corner marks, or fake text.
