Ascending Cosmic Spiral with Safe Zenith Void for Mobile Interface

Full prompt

In a 9:16 vertical portrait wallpaper composition, a complete ascending cosmic spiral is framed in its entirety within the celestial field. The vortex originates near the lower foundation with a dense, glowing nucleus of rich amber and terracotta, sending luminous plumes of deep violet gas sweeping gracefully upward along a dynamic S-curve. Translucent gaseous tendrils taper smoothly as they loop around the upper quadrant, remaining fully contained inside the canvas margins without clipping. Soft smoke-like billows exhibit convincing volumetric depth, illuminated from within by newborn stellar warmth. Deep velvet-black space envelops the entire formation, punctuated by pin-sharp, evenly dispersed field stars that emphasize the spiral's majestic isolation, fluid elegance, and tranquil cosmic atmosphere.
