用 WorkBuddy 自动化开具粤通卡 ETC 发票：浏览器接管 + 逐月批量开票实战

agent-browser 开可见浏览器（用户扫码登录）
        ↓
Playwright 用 CDP 接管同一浏览器会话
        ↓
菜单「我要开票」→ 点卡片 → 进入月份表格
        ↓
逐月设置查询月份 → 读取"可开票"行程 → 勾选
        ↓
底部「确认」→ 核对页填邮箱 → 「确认开票」
        ↓
成功页「继续开票」→ 循环下一个月

# 1. 安装浏览器自动化 CLI（全局）
npm install -g agent-browser

# 2. 下载 Chromium（较大，建议后台跑）
agent-browser install

# 3. 本机准备 Python 环境（Playwright 接管用）
python -m venv venv
venv\Scripts\pip install playwright
playwright install chromium

# Windows 查监听端口与进程
powershell -Command "Get-NetTCPConnection -State Listen | Where-Object { $_.LocalPort -gt 9000 } | Select-Object LocalPort, OwningProcess"
