Create a premium lock screen wallpaper for iPhone in a tall 9:19.5 portrait composition, target production canvas 1290x2796. Feature a lone astronaut drifting through the infinite darkness of deep space while gently holding a radiant bioluminescent cosmic jellyfish whose translucent bell glows with electric cyan, violet, magenta, and golden light, casting colorful reflections across the astronaut's visor and spacesuit. Surround the scene with a sparse star field, subtle cosmic dust, and vast negative space that emphasizes solitude, wonder, and quiet exploration. Render in a premium sci-fi digital illustration style with crisp linework, rich AMOLED-friendly blacks, luminous neon highlights, realistic space suit materials, soft atmospheric glow, and cinematic depth while preserving a clean minimalist composition. Position the astronaut slightly below center, keep the upper 20–30% almost entirely dark with only faint stars for the clock and Dynamic Island area, maintain generous side margins, avoid important details near the screen edges, and leave the lower portion clean for app icons and gestures. Exclude borders, frames, text, logos, watermarks, interface elements, and signatures while maintaining smooth gradients, controlled bloom, and a polished premium finish.
