/* ========== 青色光效应用区域总结 ==========
 * 
 * 已成功为以下卡片区域添加了从左到右划过的青色光效效果：
 * 
 * 1. CTA卡片区域 (.cta-content) - 光效强度: 0.08
 * 2. 项目成果卡片 (.project-results-inline .results-card) - 光效强度: 0.06
 * 3. 关于我们介绍卡片 (.about-card) - 光效强度: 0.07
 * 4. 服务卡片 (.service-card) - 光效强度: 0.05
 * 5. 流程步骤卡片 (.process-step) - 光效强度: 0.06
 * 6. 架构卡片 (.arch-card) - 光效强度: 0.08 【已添加到home.css，层级已优化】
 * 7. 案例卡片 (.case-content-item) - 光效强度: 0.06 【已添加到home.css】
 * 
 * 光效特点：
 * - 从左到右划过效果，悬停时触发
 * - 使用青色渐变 (rgba(14, 241, 253))
 * - 0.6秒平滑过渡动画
 * - 不同卡片区域使用不同的光效强度，保持视觉层次
 * - 所有内容元素都确保在光效之上显示
 * 
 * 技术实现：
 * - 使用 ::before 或 ::after 伪元素
 * - 通过 z-index 控制层级关系
 * - overflow: hidden 确保光效不超出卡片边界
 * - pointer-events: none 确保光效不影响交互
 * - 架构卡片和案例卡片直接在home.css中添加，避免CSS冲突
