/* 页脚吸底（内容不足一屏时页脚仍停在底部）：
   ⚠️ 不要用 `body { display:flex }` + `.footer { margin-top:auto }` 实现——
      body 变成列方向 flex 容器后，横向成为交叉轴，而 `align-items:stretch`
      **遇到 auto 外边距会失效**；`.container`/`.studio-wrap` 这类
      `margin:0 auto` 的居中容器因此退化为 shrink-to-fit，
      宽度塌成内容宽（首页曾塌到 810px / 关注页 320px），与顶部导航宽度对不上。
   正确做法：给内容容器本身一个 min-height，把页脚自然顶下去。 */
