Prompt
Minimal winter geometry: a lone black tree line across deep snow under pale light. 2026 trade-cover trend: oversized structural typography, high-contrast palette, strong readability at thumbnail size. All cover text must be English only. Book cover with title "Winter Arithmetic" and author name "Peter Sundström" 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.. 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, text too close to edges, unrelated imagery, garbled author name
