Prompt
A stopped ferris wheel at night, one gondola lit, city dark below. 2026 trade-cover trend: oversized structural typography, high-contrast palette, strong readability at thumbnail size. All cover text must be Japanese only; render the quoted title and author name in correct, complete Japanese characters. Book cover with title "沈黙の観覧車" and author name "高梨誠" rendered on the cover.. Workflow direction: Create the finished flat front-cover artwork itself, not a photograph or mockup of a physical book. The rectangular front cover must fill the entire output canvas edge to edge, viewed perfectly straight-on with the camera perpendicular to the artwork. Build a compelling genre-appropriate key image, readable title hierarchy, deliberately placed author name, short correctly rendered Chinese or English title text enclosed in quotation marks, strong silhouette at thumbnail size, and trim-safe breathing room for practical editorial use.
Style-specific direction:
Style: premium mystery-thriller book cover with cinematic noir tension and a contemporary publishing finish.
Subject: preserve the requested location, figure, clue, and era; center one charged visual mystery instead of unrelated crime props.
Composition: portrait front-cover layout, bold silhouette or symbolic object, long visual corridor, generous title-safe upper area, strong thumbnail contrast.
Lighting or Color: low-key light with one hard source and long shadows; slate blue, charcoal, and restrained sodium amber.
Typography: render the exact quoted title once in stark condensed sans-serif capitals and the exact quoted author once in small clean type; keep both crisp and correctly spelled.
Output format: flat front-cover artwork only, filling the canvas edge to edge and viewed perfectly straight-on; no physical book object, gore, police tape collage, spine, pages, back cover, perspective, mockup, badge, logo, watermark, duplicated text, or cropped lettering.. Avoid: physical book, 3D book, book mockup, product moc
