/* height:auto 必须显式声明。HTML 的 width/height 属性属于「呈现性提示」，优先级低于任何作者样式，
   但高于 UA 默认 —— 只覆盖 width 时高度仍由属性值决定，CSS 的 aspect-ratio 会彻底失效。
   实测（2026-10-14，Playwright 1440px）：首页主视觉被撑成 520x1024、详情页截图被撑成 243x1350
   （比例 0.18 的细长条），而 CSS 里明明写着 aspect-ratio: 3/4。
   显式写了 height 的规则（.logo img / .qr-row img / 图标）特异性更高，不受影响。 */

   不关掉它，5 张截图会被挤成「列2、列4 在第一行，列1、3、5 在第二行」的错位排布
   （2026-10-14 实测确认：grid item 落位 2/4/1/3/5，正是每个 picture 多贡献一个隐形格子的特征）。 */
