/* ============================================================
   阅读区布局优化 (Reading Layout) 添加 2026-07-29
   用途：优化产品详情页 / 新闻详情页在大屏下的阅读体验。将过宽且左对齐的正文
        限宽居中，并为产品标题添加一条居中渐变短装饰线，使排版更克制、专业。
   作用范围：仅作用于 .detail-title / .detail-block / .news-detail-container 三个选择器，
        绝不污染导航、卡片、首页等站点框架；合作品牌介绍框 (.brand-intro /
        .brand-intro-body) 保持原样，本段不对其做任何修改或覆盖。
   管理：搜索 "Reading Layout" 即可定位本段全部规则。
   约定：本段仅追加，不改写文件任何既有规则；颜色/间距统一引用 :root 变量；不使用 !important。
