Create a refined lock screen wallpaper for Samsung Galaxy phone in a tall 9:20 portrait composition, target production canvas 1440x3200. Design a clean retro-modern geometric pattern over a smooth deep navy-to-purple gradient, using scattered bright yellow triangles, cyan outlined circles, muted blue dot clusters, hot-pink curved arcs, and thin diagonal line accents. Keep the upper 20–30% visually calmer for the clock, widgets, centered punch-hole, and status area, with fewer bright shapes and softer pattern density around the top UI zone. Let the central field stay breathable with dark gradient negative space, while the geometric accents create playful rhythm around the sides and lower areas without becoming crowded behind icons. Use crisp flat vector edges, balanced spacing, clean color blocking, smooth gradient transitions, and controlled high-contrast accents that feel energetic but still Samsung Galaxy lock-screen readable. Keep the lower area usable for gestures, dock, and possible home-screen icons, placing large yellow triangles, hot-pink arcs, and cyan rings away from extreme edges and camera cutout areas. No text, logos, watermark, fake UI, app icons, phone mockup, border, or frame; avoid cluttered top detail, messy icon backgrounds, and accidental cropped focal shapes.
