- /**
- * 驾驶舱配置服务(票 04):后端地址、天地图、Cesium、WebSocket 与凭据的唯一读入口。
- *
- * 为什么要有这一层(spec 第 13/14 条、ADR 0005):
- * 前端不硬编码账号、密钥或环境地址;配置由部署层注入;页面与 store 只读归一化后的结果。
- *
- * 分层(后者覆盖前者,深合并):
- * 1. 内置默认 —— `dataSource: mock`(spec:默认 mock,真接口必须显式开启)
- * 2. 构建期环境变量 —— `import.meta.env.VITE_COCKPIT_*`(本机联调写 `.env.local`,已 gitignore)
- * 3. 运行时配置文件 —— `<base>cockpit/config.json`(部署时放/改,同一个构建多环境)
- * 4. 宿主注入对象 —— `globalThis.__COCKPIT_CONFIG__`(qiankun 主应用 / 网关注入;给了就不再拉文件)
- *
- * 三态:`ready`(载入成功)/ `missing`(没有任何配置来源,用内置默认)/ `failed`(拿到了但不可用)。
- *
- * 运行时文件**不会**在每次加载时盲试:没有显式配置 URL 就不发请求(否则每页都会刷一个 404,
- * 生产日志也会变脏)。要启用文件层,二选一:
- * · 宿主页加一行 `window.__COCKPIT_CONFIG_URL__ = 'auto'`(`auto` = 按应用基址取 `cockpit/config.json`,
- * qiankun / 子目录部署下都对);给绝对 URL 则直接从后端或别处拉配置;给空串 = 这个页面不要配置文件;
- * · 构建期设 `VITE_COCKPIT_CONFIG_URL`(同样接受 `auto` 或具体 URL)。宿主页的键优先于构建期。
- * 文件不存在(404)或载荷是 HTML(静态服务器的错误页)都判为缺失态,不当作故障。
