"""收货地址确认页真实 HTML 探针

走 SiteInteractor 的真实生产代码路径（add_to_cart → verify_cart → enter_checkout），
在 _confirm_default_address 被调用前把该页 HTML 落盘，验证/纠正选择器是否与真实页面
一致。**不调用 submit_order / pay**——enter_checkout 落地到确认页就返回，这里直接
丢弃该页，不产生下单动作。

用法：
    .venv/Scripts/python.exe scripts/probe_address_confirm.py
    .venv/Scripts/python.exe scripts/probe_address_confirm.py --item-url https://item.rakuten.co.jp/...
