/**
 * scripts/verify-render.mjs —— 无浏览器渲染冒烟（jsdom）。
 *
 * 为什么需要：真实浏览器验收（verify-browser.mjs）依赖 Playwright + Chromium；
 * CI / 无头环境没有浏览器时，用 jsdom 把**真实的组件树**跑起来：
 *   1. 按 index.html 的 importmap 解析裸标识符（与浏览器同一套映射）
 *   2. 导入 src/app.js → 21 个自定义元素全部注册
 *   3. 真实连 Parse（或不联网用 --offline 跳过取数）→ 三视角 / 池子 / 台账 / 报告 全部拿到数据后渲染
 *   4. 抓未捕获异常、页面错误（jsdom 不支持的能力只记录，不算失败）
 *
 * 注意：jsdom 没有 layout / backdrop-filter / IntersectionObserver，**视觉与滚动行为必须用真实浏览器验**。
 * 本脚本只回答「逻辑闭环 + 渲染不抛错」。
 *
 * 用法：node scripts/verify-render.mjs [--offline]
 *   需要 jsdom：优先用 node_modules/jsdom，其次 ../testing/node_modules/jsdom（本机验收机）
