/*
 * @Project Name: 卡尼奶主题授权插件 - 前端样式兼容层
 * @Description: knn-theme 前端缺少部分全局工具类（but/badg/jb-*/c-*/flex/间距/CSS变量），
 *               本文件补齐这些定义并桥接 knn-theme 变量体系（--knn-*）。
 *               类名与 knn-theme 主题自身输出的工具类保持一致（主题 post-frontend.php 等同款）。
 *               仅在插件购买页（body.order-pay）与前台用户中心（/account/）加载。
 *               暗色适配 knn-theme 的 body.dark-mode / body.dark-mode-auto。
