/**
 * 登录页 / 注册页（templates/auth.php）
 *
 * 【为什么写独立 CSS 而不是全用 Tailwind 工具类】
 * 这两个页不进 React 主包，也不想为它们跑一次 npm 构建（新工具类不重建就不存在）。
 * 同时避免被后加载的第三方全局工具类打穿，见 .cursor/rules/aicore-unscoped-tailwind.mdc。
 *
 * 【色值与字号取自设计 token，不是随手定的】
 * 文字 #222 / #666 / #999 / #CCC = ink / secondary / tertiary / disabled
 * 描边 #DEDEDE / #EDEDED = line / line-soft
 * 品牌 #e03030 / #c52a2a = primary-500 / 600
 * 字号 16 / 15 / 14 / 13 = body / subhead / caption / footnote
 * 标题字号不在此声明：主题 base 层的 h1 已是 display(40) + 600 + #222，直接继承。
