使用OwlCarousel无内容显示，请求排查代码问题

问题根源 #

你的代码中资源加载顺序错误：OwlCarousel 依赖 jQuery 运行，但你把 OwlCarousel 的 JS 文件放在了 jQuery 之前引入，导致 OwlCarousel 无法找到依赖的 jQuery 对象，触发脚本错误，最终页面空白。

修正步骤 #

1. 调整脚本引入顺序：先引入 jQuery，再引入 OwlCarousel 的 JS 文件
2. 初始化配置本身无问题，保持原逻辑即可

额外排查建议 #

• 打开浏览器开发者工具（F12）的控制台，查看是否有其他脚本错误
• 确认网络请求中，所有CSS和JS资源都已成功加载（无404等错误）
