   横向产品轨道 + 数据条 + 双栏服务区 + 品牌故事轮播 + 三卡赛区 + 新闻 + CTA + 页脚。
   视觉基调改成适合 SaaS 平台的暗色科技风：近黑底色 + 单一暖红强调色 + 细描边，
   全部图形（小程序界面示意、数据可视化、图标、二维码）由内联 SVG 生成，

   25 消费市场暖调主题（浅色覆盖）
   ----------------------------------------------------------------------------
   整站按「消费零售市场」的视觉语言重做配色：奶油白底 + 橙红主色 + 暖黄辅色，
   页面不再出现纯黑底和暗色科技风。1-24 分区保留原有结构与排版，本分区用同选择器
   在文件末尾覆盖颜色，改动集中在一处，方便后续单独调整或整体回退。
