   玄甲科技 / BLACKARMOR LABS — 品牌视觉层
   --------------------------------------------------------------------------
   品牌立意：「玄」者黑也，「甲」者护也。古之玄甲军以玄铁札甲护身，
   片片相缀、密不透风；今之玄甲科技以同样的编缀逻辑造实验装备——
   每一片甲是一道工序，每一处铆是一次检验，整阵列即一份可追溯的交付。

   视觉母题：札甲片（八边切角）+ 编缀铆线 + 朱砂封印
   60-30-10：玄黑 60% · 铁面 / 暖纸白 30% · 玄金 / 朱砂 10%
   单一难忘元素：首屏 ARMOR MATRIX 玄甲阵列（扫描点亮 + 中央朱印）
   字体：Cinzel（罗马碑铭）/ Bebas Neue（军工宽体）/ Noto Serif SC（宋体碑铭）
         / Noto Sans SC（正文）/ IBM Plex Mono（数据）
   本地化：内网部署请把 Google Fonts 下载到 fonts/ 后改为 @font-face
   本文件必须最后加载，用于覆盖前序样式表的颜色与形状。
