/**
 * Flock 人机协作录制 — 有头浏览器 + 分步暂停，便于熟悉流程与截图
 *
 * 用法:
 *   npm run visual:flock-human-assist
 *   $env:FLOCK_PATH_ID="F02-register-after-quote"; npm run visual:flock-human-assist
 *
 * 操作:
 *   - 浏览器打开后按 Playwright Inspector 提示继续
 *   - 每步 pause 时人工点击/填写，熟悉按钮位置
 *   - Ctrl+C 结束仍会保存 storageState 与截图目录
