Keep this photograph EXACTLY the same in every detail — same house, architecture, snow, trees, sky, furniture, composition, warm interior window glow, and all path/bollard lights unchanged. Change ONLY the color of the decorative string lights (garlands) on the house: the icicle lights hanging along the roof edges and gables, and the linear LED strips running along the eaves, balcony, and porch overhangs. Convert their warm golden/yellow light into COOL WHITE / cold blue-white light (approx 6000–7000K), like icy cold-white LED holiday lights. Preserve their exact position, shape, brightness, and glow spread — only shift the hue from warm to cold white. Do not alter anything else in the image.
