/* 苦力怕启动器官网 —— 中英两份 HTML 共用的全部样式。
 *
 * 视觉来源：Claude Design 项目 f086cbb2 的「官网.dc.html」/「Website EN.dc.html」。
 * 那两份稿子把样式全写成了内联 style（240+ 条），这里抽成语义类，一处改两站生效。
 *
 * ⚠️ 主绿是 #1f9d63，跟桌面端 app.css 的 --accent: #228965 **不是同一个值**，
 * 这不是笔误：桌面端为了浅色主题下白字的对比度把绿压暗了一档，官网按设计稿走。
 * 两者都源自苦力怕论坛主题色 #61cea8。**别顺手统一。**
 *
 * ⚠️ 原设计稿是 1440px 固定桌面稿，DC 运行时没有任何断点机制，移动端行为是空白。
 * 文件末尾那三档媒体查询是这里新加的，不是稿子里的东西。
