   行业大模型私有化部署页样式 channel_product_ai_llm.css
   结构克隆智能对话系统页;自 20261001 起 mini 基线已全量内联,本文件为唯一页面样式表。
   --------------------------------------------------------------------------
   分层:①.ai-llm-page 主题变量(#e11d48 玫红系) ②mini 结构基线(原选择器 0-1-0)
        ③.ai-llm-page 主题覆盖(0-2-0,压基线) ④场景四卡焦点布局(依赖公共 inc_scene.css)
        ⑤首屏私有大模型机房样机(模型流水线 + 三联机柜 + 盾徽,悬浮卡来自公共层)。
   约定:选择器统一 .ai-llm-page 前缀;颜色一律走变量/主题覆盖,
        禁止绿色字面值;同选择器已按声明级合并;死规则(旧样机/被替换组件)已剔除。
