/**
 * ========================================
 * 智由帮科技官网 - 全局样式表
 * ========================================
 * 
 * 文件结构：
 * 1. 全局重置和基础样式
 * 2. CSS变量定义（Design Tokens）
 * 3. 布局组件（Header、Footer）
 * 4. 轮播组件（Glide）
 * 5. 内容区域（Sections）
 * 6. 卡片组件（Cards）
 * 7. 表单和按钮
 * 8. 响应式设计
 * 9. 动画和过渡
 * 10. 工具类和辅助样式
 * 
 * 设计规范：
 * - 颜色：使用CSS变量，便于主题切换
 * - 间距：基于8px系统（8/16/24/32/48/64px）
 * - 断点：576/768/992/1100/1200/1400px
 * - 动画：默认300-500ms，使用cubic-bezier缓动
