/* =========================================================
   Your Brand — B2B 母婴纱布独立站 设计系统 v2
   ---------------------------------------------------------
   改配色只需改下面的 :root 变量。
   v2 的「大气」改动：
     · 容器 1180 → 1320px
     · 标题字号整体上探（h1 最大 68px）
     · 区块留白 76px → 最大 128px
     · 首屏改为全幅轮播，图片满屏出血
     · 新增整幅图文（split）与深色数据带
