   移动端重排 (Mobile) — 桌面样式完全不受影响
   ------------------------------------------------------------
   原响应式只有一段「桌面等比缩小」的媒体查询，手机端表现为：
   页面高达 7489px、区块间距 48px、理念卡 4 张竖排堆叠、
   「养宠指南」被从横向卡压成竖排大图卡（单这一块就 1301px）、
   评价卡两列各塞 60 字导致每行 430px、页脚快速链接 5 行。

   本次按手机阅读习惯重排，思路是「分区差异化」：
   · 卖点区块（热销好物 / 新品推荐）—— 保留两列大图卡片，
     商品图仍是视觉主角，不为了压高度牺牲转化
   · 信息区块（选品理念 / 养宠指南 / 真实评价）—— 改横向紧凑排版，
     图标或配图在左、文字在右，一行一条，大幅减少纵向堆叠
   · 分类圆形图标 3+2 落单 → 5 个一行
   · 纵向节奏：区块 48→40px，标题组 40→22px
   · 按钮触摸目标统一 ≥44px，表单控件 16px（避免 iOS 聚焦缩放）
