/* ==========================================================================
   geo-blocks.css —— GEO 内容块视觉样式
   --------------------------------------------------------------------------
   用途：为两类 GEO 结构化内容提供与站点整体风格一致的视觉样式
         1) 官方定义卡   .definition-block / .section.container[data-geo="definition"]
         2) 可抽取内容区 .section.container[data-geo="extractable"]
            （常见问题 / 操作步骤 / 方案对比表 / 关键数字）
   原则：纯视觉增强。不新增、不删除、不移动任何文本节点，
         仅通过背景、边框、圆角、阴影、间距与文字颜色改善观感，
         因此不会影响任何正文抽取规则与 GEO 判定。
   配色：来自站点变量 —— 主蓝 #185FA5 / 深蓝 #0C447C / 强调金 #EF9F27
