   这里原本有 @font-face 指向 fonts/msyh.ttf（微软雅黑，2.1MB）。
   但它只被 .marquee-content span（首页顶部滚动横幅）用到，
   而 body 的字体栈早就用的是系统字体，等于每打开一个页面
   都要白下载 2MB 只为了给一行跑马灯换个字形，得不偿失。
   现在整站走系统字体（Windows 的微软雅黑 / macOS 的苹方，
   本身就是同一个字形），省下 2.1MB 的下载量。

   注意：fonts/msyh.ttf 这个文件本身要保留 —— image_utils.php
   的服务端水印（Imagick/GD 渲染中文字）还在用它。 */

   位置：顶部滚动横幅下方、内容瀑布流上方（在 .container 内）。

   【为什么不用固定高度】
   广告图的比例由管理员自己定（可能是 6:1 的扁条，也可能是方图）。
   写死高度会导致：扁图上下留白、方图被裁掉。所以让高度跟着图片
   的原始比例走，只限制一个最大高度防止超长图把首屏挤满。

   【为什么图片要 width:100% + height:auto】
