/**
 * scripts/verify-viz.mjs —— v11b 三、P1：四类微图表（sparkline / 进度环·进度条 / 对比条 / 热力小格）实测。
 *
 * 每类都要在**真实页面位置**出现（不是造组件放着），并且：
 *   - 图不替代数字：每个图表元素旁边（父级两三层内）有可见数字文本；
 *   - 图表本身 aria-hidden（读屏只读数字）；
 *   - 不引第三方图表库（静态 grep <canvas> / chart.js / echarts / d3）；
 *   - 无渐变填充（图表元素的 background-image 里没有 gradient）。
 * 每页打印：四类图表各几个、在哪个视图、尺寸；最后截图到 docs/screenshots/v11b/viz-*.png。
 *
 * 用法：node scripts/verify-viz.mjs [--url …] [--shots docs/screenshots/v11b]
