/* ============================================================
   K31-L1 · 首页中深蓝版（用户纠正：文字纯白高亮、背景中深蓝）
   ----------------------------------------------------------------
   方向（用户明确）：
     · 文字 全部纯白 #FFFFFF，高亮清晰、不灰显
     · 背景 深蓝偏浅一档的中深蓝（介于深蓝 #1B4670 与中蓝之间）：
        主背景   #1F4E79
        浅一档   #24547E ~ #2A5A88（面板/数据条亮色层）
        深一档   #1B4670 ~ #1A4370（收口/topbar）
        页脚     #1A4370 ~ #1C486F（深蓝收尾）
     · 强调色 保留品牌红 #DF3543 / #C81E2D 作按钮/装饰；
               高亮文字用 #FFC9CE（浅粉，深蓝底上清晰不灰）
     · 过渡：整页中深蓝同族色带自上而下连续递进（hero→数据条→板块→客户墙），
             结尾平滑渐入深蓝页脚，无硬切边、无浅色断层
     · 客户墙 LOGO 沿用白卡（深蓝底上的白底 LOGO 墙，属预期对比）
    改动范围：仅本页（head/header/footer 公共文件不动，其余 PC 页面不受影响）。
