test: scope autostart retention style contract assertions

Hongzhi Wen · claude · Hongzhi Wen · commit f1e95c8f5f5b · 2026-06-06T18:56:17.000+08:00
之前断言 4 个 CSS 属性是对全文件子串匹配，而这些属性实际归属
.modal-header / .modal-footer / .modal-btn:not(.modal-btn-link):hover，
没一个在 .modal-btn-link 块里，测试名 _is_scoped 名不副实。

改成按选择器提取规则 body，在各自块里断言对应属性；同时给
.modal-btn-link 块补上它自己的契约 (position: absolute; right: 0;
bottom: 0)，即「不再提示」绝对定位到右下角的真实交付。
