   磁力天堂 (btcilitt.com)  ——  站点样式
   版式来源：参考站 hao.hsudi.com 的骨架（顶部站标导航 + Hero 搜索区 +
             常用导航图标宫格 + 分组卡片 + 页脚），按 PHP SSR 站群规范重写。
   差异化：参考站是「海浪实景照片 + 白色卡片」的浅青色调，本站改为
             「蓝紫晴空渐变 Hero + 珊瑚橙点缀」的浅色门户 —— 版式同构、观感可区分。
   规范：
     · 移动端优先，纯 CSS 实现，不依赖任何前端框架
     · 首页专用 class（hero / engine-pills / fav-grid / art-cols）与内页通用组件
       （section / lgrid / lcard / detail / pager / 后台）分区书写，互不覆盖
     · 所有可点元素的触控区、窄屏断点见文末「响应式」一节
