プロンプト
A harbor where ships from different eras moor side by side under aurora light. 2026 trade-cover trend: oversized structural typography, high-contrast palette, strong readability at thumbnail size. All cover text must be Korean only; render the quoted title and author name in correct, complete Korean Hangul. Book cover with title "시간의 항구" and author name "한겨울" 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 science-fiction book cover with cinematic speculative-world design, clearly technological rather than fantasy.
Subject: preserve the requested explorer, machine, planet, and setting; use one scientifically coherent futuristic focal idea.
Composition: portrait front-cover layout, horizon-scale environment, strong lower-third silhouette, open title-safe upper field, thumbnail readability.
Lighting or Color: deep indigo and cool chrome with one amber accent, controlled volumetric light, precise hard-surface detail.
Typography: render the exact quoted title once in tall geometric techno capitals and the exact quoted author once in smaller spaced capitals; 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, medieval runes, magic portal, fantasy crystal, spine, pages, back cover, perspective, mockup, badge, logo, watermark, or duplicated text.. Avoid: physical book, 3D book, book moc
