   ★ H5 兼容约定（改样式前先看这几条，都是踩过的坑）：
     1. 不用 CSS 变量（--x）—— 老 Android WebView 不支持时整条声明作废，
        颜色直接写死，宁可重复也别让线上翻车
     2. 不用 flex 的 gap —— flex gap 要 Chrome 84+，微信老安卓内核到不了，
        一律用「容器负 margin + 子项 padding」做间距
     3. 不用 aspect-ratio —— 要固定比例就用 padding-top 撑
     4. 不用 CSS Grid —— 统一 flexbox（Chrome 29+ 就行）
     5. 图片一律给固定宽高或 padding 撑，避免加载时页面跳动
     6. 不依赖 position:sticky，头部用 fixed + body 加 padding-top
