        .info-item .value {
            position: absolute;
            left: 50%;
            transform: translateX(-50%);
        }
        /* 小屏幕自动调整布局，避免内容重叠 */
        @media (max-width: 576px) {

关键实现思路： #

1. 定位核心逻辑：给每个信息项容器.info-item加上Bootstrap的position-relative类，作为.value绝对定位的参考容器；通过left:50%配合transform: translateX(-50%)让值精准居中在父容器内，不受内容宽度影响。
2. 响应式适配：在小屏幕（宽度≤576px，对应Bootstrap的sm断点）时，把.value改为静态定位，块级显示并居中，避免字段和值重叠，保证移动端可读性。
3. 细节优化：给.info-item添加左边距避免字段贴边，用mb-3类给信息项增加间距，让布局更清爽。
