/**
 * scripts/verify-visual-v12.mjs —— v12 深度视觉重构验收（任务书「二、硬性数值规范」逐项实测）。
 *
 * 两种用法：
 *   node scripts/verify-visual-v12.mjs --tag before    只打印现状，**不判分**（改前基线）
 *   node scripts/verify-visual-v12.mjs                  判分：任一项不达标 exit 1
 *   --page /pool       只量一页（调试用）
 *   --json out.json    结果落盘（before-after 文档从这里抄数字，不手填）
 *
 * 量什么、怎么量（每项都打印分子/分母，不打印「通过」两个字）：
 *   1. 圆角种类   所有可见元素（跨 shadow）的 computed border-radius，去重后按半径归类；只允许 0 / 8 / 12 / 20 / 9999(胶囊)
 *   2. 原生控件   button/input/select/textarea/summary：外观被显式覆盖（非 appearance:auto / 非浏览器默认灰底 / 有字族与圆角）
 *   3. 描边       可见元素的 border-width / outline-width 中 > 1px 的数量
 *   4. 纯黑       computed color === rgb(0, 0, 0) 且带可见文字的元素数
 *   5. 字号档     可见文字的 font-size 去重（容差 0.1px）
 *   6. 同排卡高   同一个 grid 容器里的直接子项，按 top 分行（±4px），行内 height 极差
 *   7. 卡内空白   卡片内部相邻两行内容之间的竖直间隙，> 24px 记一次
 *   8. hover       每个可点元素 pointerover 前后，背景色 / 边框色 / 背景图 / 颜色 / 阴影任一变化
 *   9. 底部空白    document 可滚高度 - 最后一块主内容底边
 *   10. 框内布局   筛选容器是一个整体、排序是分段控件、搜索框与筛选区底边差（P1）
 *   11. 左右等高   工作台两栏首行卡片高度差（P3）
 *
 * 注意（验收脚本的老坑，见 memory kf-verify-browser-quirks）：
 *   - 视图异步挂载：goto 后等 kf-app → view-* 的 shadowRoot 有子节点，再等 300ms；
 *   - 跨 shadow 的可见性要沿 parentElement → getRootNode().host 一路走；
 *   - hover 必须用真实指针（page.mouse.move）：合成 pointerover / mouseover 事件不会让 :hover 命中。
