/* CAEE 官网样式 — 工业感深蓝 + 金属灰 */

/* ===== 品牌色（全部取自 CAEE logo 三原色）=====
   深蓝 #004685 / 红 #FF0000 / 绿 #77B900
   角色按实测对比度分配，不是任意指定：
   · 蓝 = 结构色：栏目标签、链接、表头、标题族（白底 9.48:1，安全）
   · 红 = 行动色：按钮 / CTA / 提交 / 焦点框
     logo 原红 #FF0000 配白字仅 4.00:1（偏低），故下沉为 #D42A1F → 5.06:1
   · 绿 = 成就色：只用于深蓝底（统计数字、图标、徽章）
     深蓝底 6.64:1 出色；但白底仅 2.41:1，绝不可当浅底文字色
