Orbit of Ash — Sci-Fi Cover

Prompt

Output the flat front-cover artwork itself, not a photograph or mockup of a physical book. The rectangular cover artwork must fill the entire canvas edge to edge and be viewed perfectly straight-on with the camera perpendicular to it. Science fiction novel cover, a lone astronaut silhouette before a colossal ring gate over a crystalline alien ocean, cinematic atmosphere, cool chrome and deep-indigo palette with a single amber accent, volumetric light, painterly digital illustration, strong silhouette anchored in the lower third. The title "NIGHT CIRCUIT" is set across the upper sky in tall geometric techno sans-serif capitals with a subtle chrome bevel, and "A. VOSS" in small spaced capitals beneath. Crisp, correctly spelled, perfectly legible lettering.
