プロンプト
Create one finished science fiction front book cover in a single generation, 1024:1536 portrait composition, flat cover artwork only, never a book mockup. Exact title text: "ZERO COLONY". Exact author text: "M. A. VEGA". Subject: the first habitat dome glowing on an empty ice planet during a magnetic storm. Composition: preserve a clean title zone, one dominant focal idea, readable silhouette at thumbnail size, and professional trade-publishing hierarchy. Style: premium cinematic concept art, strong geometry, volumetric light, vast scale, restrained detail. Color and light: deep indigo, cool chrome, and one luminous cyan or amber accent. Typography: tall geometric techno sans-serif capitals with a subtle chrome edge; render the exact title and author once only, with correct spelling, clean kerning, no extra words, no duplicate letters, and no invented publisher marks. Constraints: print-ready front cover, polished visual hierarchy, coherent anatomy and perspective. Avoid: malformed text, repeated author names, extra logos, watermarks, borders, 3D books, hands holding a book, or horizontal mockups.
