/**
 * T01 浏览器交互走查（票 01 的唯一剩项）。
 *
 * 为什么不是 browser_* 工具：本机 dsh-browser 不可用 —— dsh-builtin-browser 的
 * Electron provider 需要一份可 spawn 的 Electron 二进制，而本机既没下载过
 * （node_modules/electron 下无 dist/ 与 path.txt），也装不成（GitHub / npmjs /
 * npmmirror 全部不可达，只有内网 GitLab 通）。改用已安装的 Chrome + puppeteer-core
 * 直接走查同一份页面，验证目标与票 01 的四点完全一致。
 *
 * 运行（需先起 npm run dev，服务在 http://localhost:8000/）：
 *   node .scratch/cockpit-shell-panel-layout/verify/t01-browser-walkthrough.mjs
