 * tailwind.build.css — Tailwind 工具类（离线预编译子集）
 * --------------------------------------------------------------------------
 * 为什么有这个文件？
 *  - 页面同时引入了 Tailwind Play CDN（方便你直接改类名调样式）；
 *  - 但 CDN 需要联网、且首帧会闪一下。本文件把项目实际用到的 Tailwind
 *    工具类按官方数值预编译好，保证「断网 / CDN 被墙」时页面依旧完全正常。
 *  - 数值与 Tailwind v3 官方 scale 完全一致（1 = 0.25rem，text-sm = .875rem …），
 *    所以两者同时存在也不会打架。
 *  - 想生成完整版：npm run build:css（见 README「Tailwind 构建」）。
 *
 * 颜色 token 直接映射到 assets/css/tokens.css 的 CSS 变量，
 * 因此所有工具类都天然支持 6 套主题 + 深色模式。
