Christmas Wallpaper — Snowy Cabin at Night

A vertical 9:16 Christmas phone wallpaper: a small log cabin with smoke rising from the stone chimney and a wreath on the door, sitting in deep fresh snow at night in a pine forest clearing. Output resolution: 4K ultra-high definition, vertical portrait orientation for a phone lock screen. Composition: the cabin anchored in the lower third, slightly off-centre; the upper half is open starry night sky with a faint ribbon of northern lights with nothing busy in it, so the clock sits on a calm area; the bottom edge falls into soft blue shadow so the icon dock stays readable. Lighting: warm amber light glowing from every window and spilling onto the snow in long soft rectangles, against cold blue moonlight everywhere else — the warm/cold split is the whole mood. Detail at 4K: individual snow crystals catching light on the roof edge, frosted pine needles on the nearest trees, wood grain on the cabin logs. Atmosphere: light snow falling, flakes blurred where they pass close to the lens. Colors: deep navy, cold blue-white and warm amber only. Finish: photographic, gentle film grain, no HDR halos. No text, no watermark, no logos.
