   即刻智能官网 · 决策增强层（jk-conv.css）
   ------------------------------------------------------------
   作用：在 React 首页的「服务客户」与「开启您的数智化工厂之旅」之间
        插入 4 个区块：客户全景 / 双线痛点 / 四组证据 / 预约诊断。
   约束：
     ① 全部规则挂在 #jk-conv 下，不改动站点既有样式；
     ② 不用 grid / gap / inset / clamp，改用 flex + 百分比宽度，
        兼容 Chromium 49+（百度系 / 微信 X5 老内核）；
     ③ 配色沿用站点：底 #050508、主色 #0071E3、正文 rgba(255,255,255,.62)。
