 - VPS 数据持久化在 `/opt/ai-toy-patent-workflow/data`
 - VPS 生产环境变量在 `/opt/ai-toy-patent-workflow/deploy/.env.production`，不入库
 - 资源索引：运行 `npm run resources:index` 生成 `data/resource-index.json`、`data/resource-index.md` 和 `data/named/` 人类可读软链接；原始资源文件名不能直接改，避免 session JSON / 图片 URL 断链
+- 风格示意图：运行 `npm run styles:previews -- --force` 用 GPT 图片模型生成 `public/style-previews/*.png`；UI 左侧风格卡片直接引用这些小图
 
 ## 环境变量
 - `OPENAI_API_KEY` — GPT API Key；文本/结构化/图片生成统一走 GPT 最高规格配置
