/* ==========================================================================
   星科罗智能 · 服务项目模块
   --------------------------------------------------------------------------
   用途：替换原「客户与合作伙伴的真实评价」模块，展示六个落地案例。
   依赖：bootstrap 栅格、animate.css(wow)、premium-theme.css 的色板 token。
   回退方式：删除 index.html 中本文件的 <link> 即可去掉本模块所有样式。
   设计原则沿用 premium-theme：白底 + 1px 细边卡片，荧光绿只做 2px 装饰线。
