   华跃无纺布 · 统一设计系统 v2 ——「现代生态工业风」
   --------------------------------------------------------------------------
   设计原则(参考国际 B2B 制造企业官网):
   1. 60-30-10 色彩法则:60% 纯白/浅灰绿背景 + 30% 深松绿标题 + 10% 琥珀金 CTA
   2. 沉稳专业的深绿主色系,体现环保材质与工业信任感
   3. 大留白、模块化网格、圆角卡片、柔和阴影,营造高级质感
   4. 深色页脚收尾建立品牌权威感,金色点缀传递高端定位
   5. 全站响应式:桌面端多栏、平板双栏、手机单栏自适应
