ناطحة سحاب مستقبلية تحت سماء مرصعة بالنجوم

A [4K vertical smartphone wallpaper] featuring a dramatic low-angle street-level perspective looking up at a single futuristic skyscraper, using the mood and lighting of the reference photo. The tower showcases sleek curved glass architecture, purple reflective panels, warm gold edge lighting, and exactly three tall sail-like vertical spires rising toward the sky. In the background, a clear cosmic night sky features a visible Milky Way band, dense stars, and soft purple nebular clouds near the horizon. At the street level, a polished plaza base features warm illuminated entrances, subtle landscaping, and glossy ground reflections. Luxurious sci-fi architectural style, purple-and-gold color palette, ultra-detailed realism, cinematic high-contrast lighting, no text, no watermarks.
