undefinedGenre Conventions
体裁规范
Readers judge books by covers. Matching genre expectations is critical — a romance reader will skip a cover that looks like sci-fi, regardless of content.
读者会以貌取“书”。契合体裁预期至关重要——即使内容再好，浪漫小说的读者也会跳过看起来像科幻风格的封面。

Spine Width
书脊宽度
Approximate: page count / 400 = spine width in inches (varies by paper stock).
- 200 pages ≈ 0.5" spine
- 400 pages ≈ 1.0" spine
大致计算方式：页数 / 400 = 书脊宽度（英寸）（因纸张材质而异）。
- 200页 ≈ 0.5英寸书脊
- 400页 ≈ 1.0英寸书脊

└─────────────────────────┘The Thumbnail Test
缩略图测试
Your cover will be seen at 80x120px on Amazon, 60x90px in search results, and ~40x60px on mobile grids.
At thumbnail size, readers must be able to identify:
- The genre (from color and composition)
- The title (if large enough)
- The mood (from imagery)
Test: shrink your cover to 80px wide. If you can't read the title or identify the genre, redesign.
你的封面在Amazon上会以80x120像素展示，搜索结果中为60x90像素，移动设备网格中约为40x60像素。
在缩略图尺寸下，读者必须能够识别：
- 体裁（从配色和构图判断）
- 标题（如果字号足够大）
- 氛围（从视觉元素判断）
测试方法： 将封面缩小至80像素宽。如果无法读取标题或识别体裁，就需要重新设计。

排版规则
AI cannot render text reliably. Generate the cover art/background with AI, then add typography in a design tool.
AI无法可靠生成清晰文字。 先用AI生成封面插画/背景，再用设计工具添加文字。
Title Hierarchy
标题层级
- Title — largest, most prominent, top 1/3 of cover
- Subtitle — smaller, below title or at bottom
- Author name — bottom of cover, size depends on author recognition
- 书名 —— 字号最大、最醒目，位于封面顶部1/3区域
- 副标题 —— 字号较小，位于书名下方或底部
- 作者名 —— 位于封面底部，字号取决于作者知名度
Font Pairing by Genre
分体裁字体搭配
- Thriller: bold sans-serif title + condensed sans-serif author
- Romance: script/cursive title + elegant serif author
- Sci-Fi: geometric sans-serif for both
- Fantasy: decorative/medieval serif title + clean serif author
- Business: heavy bold sans-serif title + light sans-serif subtitle
- 惊悚类：粗体无衬线书名 + 窄体无衬线作者名
- 浪漫类：手写/草书书名 + 优雅衬线作者名
- 科幻类：几何无衬线字体（书名+作者名）
- 奇幻类：装饰性/中世纪风格衬线书名 + 简洁衬线作者名
- 商业类：粗体无衬线书名 + 轻量无衬线副标题

| Centered everything | Static, boring | Use asymmetry intentionally |
| Following trends blindly | Dates quickly | Classic genre conventions endure |
| 错误 | 问题 | 解决方法 |
