Take the interior scene from the second uploaded image (a bathroom vanity area with a white pedestal sink, gold-framed mirror, brass sconce, and lower wainscoting) and completely replace the plain upper wall background with the exact geometric wallpaper pattern from the first uploaded image (sage green and cream nested diamond/rhombus pattern). Ensure the wallpaper pattern is extremely crisp, sharp, highly detailed, and realistically mapped to the wall, interacting naturally with the light and shadows. Update the colors of the architectural elements based on the palette in the third image: paint the lower wainscoting/beadboard panels and any trim in a muted 'Soulful Sage' green (#A8AE9B) to perfectly complement the wallpaper. Preserve all other original elements perfectly: the white sink, brass fixtures, mirror with its reflection, sconce, flowers in the vase, the hanging towel, and the realistic natural sunlight. Photorealistic, 8k resolution, seamless blending.
