Create a dramatic lock screen wallpaper for iPhone in a tall 9:19.5 portrait composition, target production canvas 1290x2796. Form a deep-space black hole scene with a luminous silver-white spiral vortex centered slightly below the middle, its bright accretion trails curling inward toward a smooth dark void while dense star particles and faint cosmic dust recede into a near-black background. Use deep black, charcoal, cool blue-gray, graphite, soft white, silver, and tiny warm amber star accents to create a hypnotic cosmic mood with strong orbital motion and elegant dark-screen contrast. Keep the top 20–30% visually calmer for the clock and Dynamic Island zone, using smoother black space, fewer stars, softened dust, and no harsh white particle clusters directly behind the upper UI area. Preserve the full spiral shape away from extreme screen edges, keep the central void slightly below the main clock zone, and leave the lower area clean for gestures, dock, and possible app icons with no watermark-like marks. Favor rich OLED-style blacks, smooth cosmic gradients, controlled star density, crisp but not over-sharpened spiral strands, and restrained white bloom for a polished iPhone display. No text, no logos, no watermark, no signature, no fake interface elements, no phone mockup, no decorative border or frame.
