A hotel corridor at night where every door is identical except one, slightly open. 2026 trade-cover trend: oversized structural typography, high-contrast palette, strong readability at thumbnail size. All cover text must be Chinese only; render the quoted title and author name in correct, complete simplified Chinese characters. Book cover with title "第十三个房客" and author name "陆知非" 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 one compelling genre-appropriate key image on a single strong subject in a single scene — never a collage of competing motifs. Follow the 2026 trade-cover direction: oversized structural title typography treated as part of the artwork, a high-contrast palette, an author name placed deliberately and secondary to the title, short correctly rendered title text in the requested language enclosed in quotation marks, and a silhouette that stays readable at 100-pixel thumbnail size in a two-second scroll, all with trim-safe breathing room.
Style-specific direction:
Style: premium mystery-thriller book cover with cinematic noir or dark-academia tension and a contemporary publishing finish; the author name reads as a brand element.
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; grounded photorealism where it deepens the dread.
Typography: render the exact quoted title once in stark condensed sans-serif capitals at commanding scale and the exact quoted author once in clean spaced type placed with brand confidence; 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 mockup, spine, pages, page edges, back cover, perspective view, angled cover, tabletop, pedestal, hands holding a book, room scene, drop shadow around the cover, misspelled title, crowded typography, weak focal point, busy collage of competing motifs, washed-out low contrast, text too close to edges, unrelated imagery, garbled author name, misspelled or cropped title, misspelled author, duplicated text, landscape layout, gore, generic police collage, mockup, spine, watermark
