   2026-09-21 移动端卡片统一改「左图右文」（只影响 ≤768px，桌面端一行未动）
   本页 2 类卡片原本是「图标/序号在上 → 标题 → 描述」竖向堆叠，手机上一屏信息太少、整页很长。
   改法与首页「为什么选择」、商城页一致：左列固定 44px 放图标/序号，标题与描述落在右列，文字左对齐。
   实现要点：
   1) grid 左列 44px，第二列用 minmax(0, 1fr) 防止窄列被撑破；
   2) 图标 grid-row: 1 / span 2 —— 在「标题 + 描述」两行范围内纵向居中（短卡片＝整体居中，
      长卡片（带列表/长正文）也不会飘到卡片中间，始终贴着标题；row-gap 为 0，空行不撑高卡片；
   3) 右列只列「确切存在的子元素」（标题/正文/列表），未列出的（绝对定位的序号水印、徽标）
      保持原样，仍相对卡片 padding 盒定位，不会被挪位、也不会被塞进右列。

   2026-09-21 移动端 CTA（「给我们一次演示机会，您再做出选择！」联系区块）上下留白收紧
   原来手机上直接沿用桌面值（各页 70 / 80 / 100px），390px 宽下这块内容只有 3~5 行，
   上下各留一大块空白，很空、不紧凑 → 移动端统一收到 40px（约一半），桌面端一行未动。
   ⚠️ 必须写在**页面 CSS** 里：style.css 的媒体查询会被页面 CSS 的基础规则
