/* Tailwind CSS 2.2.19 最小子集（本地内置，勿手工编辑细节）
 *
 * 背景：login / pkce-login / cdkey-query / cdkey-admin / logout-test 原本从
 * cdnjs.cloudflare.com 引入全量 Tailwind（未压缩约 2.9MB）。该 <link> 位于 <head>
 * 且为渲染阻塞资源，国内访问该 CDN 经常超时，表现就是整页白屏。
 * 这几个页面实际只用到约 110 个 utility 类，因此本地内置一份精确子集。
 *
 * 内容来源：
 *   1. preflight  —— 原样截取自 tailwindcss 2.2.19（保证移除 CDN 后渲染不变）
 *   2. utilities  —— 从 2.2.19 中按“项目实际用到的类名”精确提取，规则逐条保持原样
 *
 * 维护方式：
 *   - 新增页面样式优先写进各页自己的 css/*.css，不要往这里加。
 *   - 确实需要 Tailwind utility 时，把类名补进页面/JS，然后按下面的方式重新生成
 *     （见 docs 或直接跑仓库根目录脚本），不要手写近似规则，否则与 Tailwind 不一致。
 *
 * 注意：Tailwind v3 的语法（bg-white/5、w-[180px] 等）在 2.2.19 中本来就不存在，
 *       本项目历史上一直是 no-op，这里同样不提供，避免引入视觉变化。
