/* =========================================================
   库库出海 · 官网主页 · 图鉴蓝本版（Ops Field Manual v11）
   ---------------------------------------------------------
   设计方向：Editorial Art Direction × Product-led × Precision Grid
   - 全页单一「暖纸白」光世界，以墨黑发丝线分区（不再明暗交替）
   - 墨黑超大编辑排版（Hero 88px）+ 橙色「信号标记」克制点缀
     （marker 高亮 / 索引编号 / 唯一主 CTA / 状态点）
   - 首屏产品视觉 = 全出血「控制台画布」：主窗口 + 指纹工厂 + AI 作曲器
     三窗层叠、等宽字体标注，突破内容容器宽度
   - 等宽字体承担元数据（版本 / 索引 / 状态 / 标注）
   - 核心业务 = 四种节奏变体章节（大图交错 / 反转 / 全出血墨带 / 双联卡）
   - 覆写 style.css 全局 token（仅本页生效；admin 不加载本文件）
   复用既有类名与 JS 钩子；可见中文文案零改动（i18n 以中文原文为 key）。
