dsh-background：在 DeepSeek Harness Web 中配置本地背景图
dsh-background 是 DeepSeek Harness Web 的一个 MIT 许可证插件，旨在让用户通过本地图片自定义网页背景，同时保留默认主题和文字可读性。安装后，用户可在“设置 → 通用设置 → 外观”中填入本地图片绝对路径，并调节 0–100% 的蒙层强度以优化显示效果。插件支持 jpg、png 等常见格式（上限 25MB），具备实时预览、明暗主题自动适配及配置持久化功能。由于浏览器无法直接读取本地文件，图片由宿主端通过 `/dsh-background/image` 路由提供。该插件适合需要本地化背景且不直接修改源码的场景，安装前建议审查源码安全性，卸载后需手动清理配置文
