/**
 * 黄瓜吧 风格 CSS — Style B: Fresh（方案 A · 清新，2026-10 改版）
 * 黄瓜绿主色 + 浅色导航 + 发丝边框 + 系统字体栈
 *
 * 生成方式：以 style-a.css 为底稿（结构、交互、各页面样式全部沿用），
 *   1) 替换下方 :root / html.dark 设计 token；
 *   2) 把底稿里写死的珊瑚橙替换为 token；
 *   3) 文件末尾「方案 A 覆盖层」按设计稿精修各组件。
 * 回滚：includes/header.php 里把 style-b.css 改回 style-a.css 即可（style-a.css 未改动）。

/* ===== 视频灯箱：图片+视频混排网格里的视频格子被压得很小，点击后弹出放大播放 =====
 * 结构与图片灯箱（.lightbox）一致，复用同一套 z-index/关闭按钮样式，区别只在内容是
 * Plyr 播放器而不是 <img>。
 *
 * 尺寸这里踩过一个坑：一开始把 .plyr/.plyr__video-wrapper/video 都强制 width:100%
 * 撑满容器宽度，只用 max-height 兜底。但 <video> 按 HTML 标准默认就是
 * object-fit:contain——"按原比例居中显示，播放区里视频之外的地方什么都不画"，
 * 也就是浏览器会自己拿播放器的黑色背景去补那部分空白。一旦视频真实宽高比跟这个
 * "先撑满宽度再兜底高度"算出来的框不一致（尤其手机竖拍的视频，先前那 800px+ 的宽度对它
 * 完全用不上），播放器自己的黑边就会大到很显眼——不是灯箱本身画的黑框，是 <video>
 * 元素在它自己被强行撑大的框里补的背景色。
 *
 * 正确做法是反过来：不强撑宽度，让 .plyr/.plyr__video-wrapper/video 全部
 * width:auto;height:auto，只给 <video> 一个视口单位的 max-width/max-height
 * （不依赖父级尺寸，随时能解出确定值），播放器的框会跟着视频真实宽高比自己收缩到
 * 刚好包住内容，灯箱背景本来就是深色半透明，视频周围不会再多出一块突兀的黑框。
 *
 * 这里还有个 Plyr 自己的坑：它会新建一个外层 <div class="plyr plyr--video ...">
 * 包装器（真正决定播放器整体尺寸的是它），但原来那个 <video class="plyr"> 标签本身
 * 依然保留着 "plyr" 这个类不会被摘掉。也就是同一个页面里有两个元素都命中 ".plyr"——
 * 外层包装器和内层 <video> 本身。如果直接写 ".plyr{...}" 会同时套在这两个元素上，
 * 而且因为多一层嵌套关系，优先级还会盖过专门给 <video> 写的规则，
 * 把视口单位的 max-height 顶掉，导致视频按原始像素铺满、又被 <video> 自己的
 * object-fit:contain 兜出一圈黑边——正是这次要修的问题。改用 .plyr--video
 * 这个只有外层包装器才有的状态类来点选它，避免和内层 <video> 撞选择器。
