/*
 * FluxSwap 案例详情页专属样式 —— template-parts/case/fluxswap.php。
 *
 * 这份设计稿和奶龙那套（rich-page.css 的 fl-cd-*）版式差别很大：
 * 标题居中、内容块直接落在页面底色上而不是包一层白卡、数据区是 bento 栅格、
 * 评价区是横向轮播。硬套 fl-cd-* 只会互相打架，所以另起 fl-fx- 前缀单独一份，
 * 由 functions.php 按「案例 slug 有同名 CSS 就入队」的规则只在本页加载。
 *
 * 只有按钮（fl-cd-btn*）继续复用 rich-page.css，站内按钮手感保持一致。
