   gateway 产品页样式(克隆自 data-platform 标杆页) channel_product_iot_gateway.css
   结构克隆腾数小程序页;自 20261001 起 mini 基线已全量内联,本文件为唯一页面样式表。
   --------------------------------------------------------------------------
   分层:①.iot-gateway-page 主题变量(#ea580c 蓝紫系) ②mini 结构基线(原选择器 0-1-0)
        ③.iot-gateway-page 主题覆盖(0-2-0,压基线) ④场景四卡焦点布局(依赖公共 inc_scene.css)
        ⑤首屏独立构图「硬件产品台」(CSS 绘制网关盒子+硬件规格协议栈+采集上云数据流,悬浮卡来自公共层)。
   约定:选择器统一 .iot-gateway-page 前缀;颜色一律走变量/主题覆盖,
        禁止绿色字面值;同选择器已按声明级合并;死规则(旧样机/被替换组件)已剔除。
