Create a clean lock screen wallpaper for Samsung Galaxy phone in a tall 9:20 portrait composition, target production canvas 1440x3200. Build a minimalist night cloud illustration with a vast pure black upper sky and layered rounded cloud forms rising from the lower half, using bright white foreground clouds, pale blue-gray mid layers, slate-blue shadow shapes, and deep navy cloud masses near the bottom and sides. Keep the upper 20–30% almost completely black and low-detail for the Samsung Galaxy clock, widgets, status area, and centered punch-hole region, with no bright cloud highlights behind the UI. Place the brightest white cloud clusters below the upper interface zone, letting the clouds build upward in soft overlapping volumes while preserving generous black negative space above. Keep the lower area readable for gestures, dock, and possible app icons by using darker navy cloud layers near the bottom and avoiding dense high-contrast detail at the edges. Render the scene as a polished AMOLED-dark cloud wallpaper with smooth cel-shaded gradients, rounded clean cloud edges, soft moonlit depth, controlled white highlights, and no stars, moon, birds, people, buildings, readable text, logos, fake UI, app icons, borders, frames, or phone mockup.
