   关键词：黄漫画
   域名：huangmanhua.net.cn
   配色：宣纸白底 + 藤黄 + 黛蓝 + 朱砂红点缀
   ============================================ */

/* ⚠️ 内容安全警示：本站仅面向成年用户访问，页面视觉不包含任何成人内容素材 */
/* ============================================
   设计理念：
   · 宣纸纹理质感 — 米白底 + 细颗粒噪点（用CSS模拟）
   · 东方卷轴叙事 — 横向滚动的"卷轴式"漫画库展示
   · 水墨晕染交互 — 鼠标悬浮产生墨点扩散效果
   · 印章式强调元素 — 红色方章作为品牌印记
   · 大字重对比 — 极粗标题 + 极细正文，制造张力
