  ② 等联想列表出现 → 用鼠标点「${pickupLabel}」
     或键盘：↓ 移到目标 → 浏览器里 Enter（不是终端 Enter）
  ③ 确认提货锁定后，终端检查点 pickup 按 Enter
  ④ 派送框输入：${pair.delivery.street}, ${pair.delivery.city}, ${pair.delivery.state}
  ⑤ 点选「${deliveryLabel}」或 ↓+Enter
  ⑥ 终端检查点 delivery 按 Enter

终端 Enter 仅用于检查点；浏览器 Enter 才用于选联想。
录证成功标志：检查点日志出现 selectionClicks>=1 或 selectionKeys 含 Enter@INPUT
