/* 组件实现说明：
 * 顶部导航保持品牌、核心分类与客户端下载入口的清晰层级。
 * 首屏以检索和分类为先，不使用大幅轮播占用有效浏览空间。
 * 海报容器固定为二比三比例，缺少图片时仍保留稳定布局。
 * 卡片使用细描边和低明度差区分层级，避免厚重阴影干扰。
 * 主色用于观看主线与关键按钮，亮青用于工具入口和信息状态。
 * 下载页使用独立卡片和安装核对步骤承载设备端信息。
 * 所有交互控件保留清晰的键盘焦点状态。
 * 移动端重排导航、卡片列数和下载卡片，不单纯缩小桌面布局。
 * 减少动态效果设置尊重系统级减少动态偏好。
 * 正文色与次级文字色在深色背景上保持可读对比。
 * 主要容器宽度统一，避免不同页面横向边界错位。
 * 页面不依赖第三方字体、图标库或 CSS 框架。
 * 站内入口使用实际 PHP 文件地址或有效页面锚点。
 * 搜索增强失败时服务端输出的核心正文仍然存在。
 * 分类标签在窄屏下自然换行，避免横向溢出。
 * 海报图片采用 object-fit:cover，避免素材比例不一致破坏网格。
 * 页面底部保留品牌说明与实际站内导航。
 * 下载中心明确展示未提供安装包地址的状态，不制造虚假链接。
 * 全站可见文案使用简体中文，必要技术缩写除外。
 * 样式变量集中定义，便于后续按品牌规范维护。
