   晓之俱乐部 · AI 应用（apps）视觉层  apps.css
   ------------------------------------------------------------------
   版式严格对齐参考站 aitudou.cn 的 AI 应用（ToolsView / ToolDetailView）：
     列表页：品牌横幅 → 精选 Hero 大卡 → 双排筛选栏（分类 chips / 搜索 + 网格·列表切换 / 类型 chips）
            → 三列卡片网格 / 列表视图 → 空状态
     详情页：面包屑 → hero（左文案 + 右封面）→ 成果图集 → 应用说明 → 访问信息面板 → 获取弹层
     6 个应用共用同一模板与同一套类，界面完全一致。
   配色沿用傻牛「奶油 + 棕褐 + 暖橙」令牌（theme.css / pet.css）。

 *  inline SVG 无显式尺寸时按容器拉伸 → .xa-feat-eyebrow 里的 spark 图标实测涨到
 *  474x474px，视觉上像一个占满半屏的 loading 转圈。
