Using the second uploaded image as the base interior scene, completely replace the plain wall background with the exact geometric wallpaper pattern from the first uploaded image (sage green and cream nested diamonds). The wallpaper must be mapped perfectly onto the walls without distortion, maintaining the correct scale, texture, and perspective of the room. Strictly preserve all existing furniture, decor, and architectural elements from the second image: the built-in bench with striped cushion, brown throw pillow, dark wooden chair and table, bamboo window blinds, brass wall sconce, vase with greenery, and the grey-green window trim and lower paneling. Maintain the original photorealistic lighting, natural sunlight, and shadows interacting realistically with the new wallpaper. 8k, highly detailed, photorealistic seamless blending.
