 - 外部引擎 URL 必须以 `http(s)://` 开头并包含 `{query}`，否则后端 400。
 - 引擎 id 只能用小写字母 / 数字 / `-` / `_`（1–30 位，`internal` 保留）；内置五个用品牌图标，
   后台新加的引擎 id 自动生成为 `custom-xxx`、图标用通用地球（组件库 EngineIcon 自动回落）。
+- 每个引擎可带 `icon`（png / svg 地址，`/` 开头的托管路径或 http(s) 链接）：给了就用 `<img>` 渲染自己
+  的图标，留空回落到品牌图标 / 地球；SVG 走 img 是静态的，不执行脚本。
 - `background.light/dark` 为空时用内置 `stash-web/src/assets/site-bg.jpg` / `site-bg-dark.jpg`；否则填托管目录 `public/` 路径或完整 URL。
 - 旧 settings JSON 缺失字段会自动回落默认值；多余旧字段在下次保存时被丢弃。
