Use case: style-transfer. Create ONE new portrait 9:16 pixel-art mountain background for our vertical climbing game. Attached PNG is the APPROVED STYLE reference, not geography to copy. Match its crisp small connected pixel clusters, detailed terrain planes, controlled warm dawn light from upper left, cool blue/lavender shadows, layered atmospheric depth. No blur, no photorealism, no smooth vector art or plastic 3D. Full bleed tall composition, summit around 22-27% from top with ample sky, environment continuing naturally to bottom. Background must remain quiet enough for an orange pixel climber and platforms. No UI, no text, no labels, no people, no floating platforms, no logos. Preserve the particular mountain morphology described below. Natural earth/vegetation colours are allowed; do not recolor every landscape uniformly blue. Real MONT BLANC from the Chamonix/Aiguille du Midi side. A broad rounded white summit DOME behind lower serrated ridges, expansive glaciated shoulders, stepped serac fields and deep glaciers, dark granite ribs; asymmetric multipart massif. The highest summit must be softly rounded, NOT a sharp generic pyramid and NOT a volcano. A dramatic pale-blue ice stream curves through a rocky valley below, subdued pine valley at the very bottom. Warm peach rimlight on the rounded upper snow, blue-grey rock and cool lilac ice. Preserve believable huge Alpine scale, recognizable dome rising above its ridge system.
