Foto-Linie Innenraum-Zusammenführung: Realistisch zu Skizze-Verlauf

Create a full-frame left-to-right fading comparison from the input photo: one side retains high-fidelity original photography with real materials, while the other side gradually degrades along the same perspective, same object positions, and same light direction into ultra-fine black hand-drawn line art, with furniture, architecture, plants, and objects keeping only structural outlines and sparse cross-hatching; the gradient transition naturally passes through objects, no hard cuts, no duplicated second scene. Background uses warm off-white paper texture with minimal original photo color patches, add one handwritten observation, no extra decoration, corner marks, or fake text.
