 生产环境不会使用 Vite 的开发代理，需要在 Nginx 或其他网关中配置同样的 `/api` 反向代理。Mock 开关按业务模块（对齐菜单）拆分，缺省使用演示数据的只有签署侧（签署工作台 `VITE_MOCK_SIGNING`、签署记录查询 `VITE_MOCK_SIGN_RECORDS`）与「报表分析」目录下的四个菜单（`VITE_MOCK_REPORT_ANALYTICS`，后端没有分析聚合接口），其余模块直接调用真实后端；各开关的环境变量名与缺省值见 `src/utils/mock-flags.ts`，需要临时切换时在本地 `.env.*.local` 里覆盖即可。使用本地开发代理时，`VITE_API_BASE_URL` 应填写 `/api`；如果改为直连后端，则需要后端配置允许当前前端源的 CORS。
 
 当前尚未接入的签署能力包括手写板设备桥接、线上签署页面/签名回调和打印服务。签署投递、一次性 Token 消费和真实 PNG 上传 API 已完成封装，但页面不能用 Canvas 演示数据冒充真实签名；需要接入设备适配器或患者 H5 回调后再启用。短信初次发送接口需要完整手机号，而患者查询只返回脱敏手机号，因此真实模式会要求当前操作人员确认完整投递地址；生产环境也可以改为由后端根据患者 ID 解析投递地址。签署工作台缺省即使用演示数据（`VITE_MOCK_SIGNING`），需要走真实投递时把它设为 `false`。
+
+文档库正文编辑器：选中「患者签名」占位符后，可以自动识别 PDF 位置，或生成 PDF 预览后输入坐标。阴影框支持拖动定位，宽高输入即时更新；点击「更新该项」或保存正文写入位置。正文变化后需重新生成预览。预览使用示例患者，实际患者文字长度可能影响排版，建议为填写项预留固定空间。重复的患者签名占位符不会自动选取。后端在保存及发布时检查页码与页面边界。
