   2026-08-26 推倒重设计
   ────────────────────────────────────────────
   设计概念：工程档案库 / 专业工程刊物
   - 暖纸白底 #FAF9F5（告别纯白 SaaS 感）
   - 墨青主色 #0F3D3E（刊头/页脚/标题锚点）
   - 强调绿 #0E9F6E（链接/CTA/hover）
   - 沙金 #B8935A（编号/徽章/kicker）
   - 蓝图网格背景（hero，CSS 纯绘制工程图纸感）
   - 刊头式双栏 header、mono kicker、超大标题
   - 卡片细边框零阴影，hover 墨青反转
   - 类名 100% 兼容旧版，34k 页面无痛换装
