プロンプト
Create one finished mystery thriller front book cover in a single generation, 1024:1536 portrait composition, flat cover artwork only, never a book mockup. Exact title text: "NO WITNESSES". Exact author text: "ELI CROSS". Subject: an empty subway platform with a dropped red glove near the yellow safety line. Composition: preserve a clean title zone, one dominant focal idea, readable silhouette at thumbnail size, and professional trade-publishing hierarchy. Style: tense film-noir realism, hard directional light, fog or rain, uncluttered focal mystery. Color and light: charcoal, slate blue, and one controlled red or sodium-amber accent. Typography: stark condensed sans-serif capitals with tight tracking; 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.
