/* 法律文件页（中文站）：privacy.html「隐私与安全」与 terms.html「使用条款」共用。
 * 英日站仍用 subpage.css 里的 .legal-page 旧样式，两份样式互不影响。
 * 结构：首屏（面包屑 → H1 → 导语 → 日期 → 文件切换）→ 左侧目录 + 右侧正文（编号章节、安全措施卡片、联系方式）。
 * 字号走全站阶梯变量，断点里只重定义变量；正文取 16px 阅读字号（与详情页一样单独设定）。
 * 踩坑提示：subpage-system 的 body.subpage :where(p, li) 会把段落涂灰，design-tokens 的 .subpage :is(p, li) 会压行高，
 * ≤700px 时 .subpage :is(button, a) 不换行，closing-section 里的链接会被涂成蓝底——对应规则都在本文件显式还原。
