/* =========================================================
   HNYZ · 衡南一中编程社 — 蓝白科技风样式
   ---------------------------------------------------------
   设计要点：
   1. 蓝白配色：浅蓝背景 + 白色卡片 + 深海军蓝文字
   2. 主色 #2563eb，辅助深天蓝 #0369a1
   3. 项目卡片：16:9 封面、3 行简介、等宽字体数据栏
   4. Hover：边框高亮 + 柔和蓝色投影 + 轻微上浮
   5. 移动端：900px 切换菜单，1020 / 720px 调整网格

   所有颜色集中在 :root，想换主题只改变量即可。
