/**
 * scripts/check.mjs —— 静态体检（部署前，对应任务书第 5 节 A 组 1–9 项 + C 组凭据红线）。
 *
 * 做什么：
 *   1 无装饰器语法            2 相对 import 全带 .js（且目标文件存在）
 *   3 无 window.KF_*          4 无 innerHTML
 *   5 core 不碰 DOM / fetch   6 视图层不直接 fetch
 *   7 base href / importmap 前缀 / 部署前缀 三处同源
 *   8 无 @lit-labs/router     9 lit 单实例（importmap 只有一个版本路径）
 *   C 前端无凭据（masterKey / 密钥值）
 *   附：语法 node --check、裸标识符都在 importmap、自定义元素标签带连字符、define 幂等、
 *      wc 组件全部 extends LitElement（禁原生 wc 手写）
 *
 * 用法：node scripts/check.mjs [--env prod]
