 * 问题排查指南：
 * 1. 如果发现元素仍有 transform: translateY()，可能是 JavaScript 动态添加的
 * 2. 在浏览器控制台运行以下代码检查：
 *    document.querySelectorAll('.hero, .hero-content, .hero-text, .hero-image').forEach(el => {
 *      const style = window.getComputedStyle(el);
 *      if (style.transform !== 'none') {
 *        console.warn('发现 transform:', el.className, style.transform);
 *      }
 *    });
 * 3. 检查是否有其他 CSS 文件覆盖了这些样式
 * 4. 检查是否有 JavaScript 文件在滚动时添加 transform
