/* ==========================================================
   宣讲会 / 内推 / 雇主品牌 页面样式 v2（2026-10-15 重做）
   ----------------------------------------------------------
   v1 的问题（截图看出来的）：hero 背景用 luminosity 混成一团灰；
   日期与时间被拆成两行；卡片靠 1px 灰边框撑，层次单薄像文档；
   热招方向就是一排白按钮；说明区是大段文字。
   v2 参考大疆/腾讯/阿里/美团/字节的校招站重做：
     · hero：全屏图 + 居中/左对齐超大字标语 + 品牌色高亮关键词 + 只留 2 个 CTA
     · 顶部公告条（活动通知）
     · 大圆角卡片 + 阴影分层，弱化边框
     · 日期用大号数字色块；日程走时间轴
     · 图标卡网格替代裸按钮；三步流程卡
   ⚠️ 首页仍在用的 .home-promo / .hp-card / .bp-strip / .bp-facts 保留在本文件里。
