/* ==================================================================
   智慧养育（0-3 岁成长记录）样式
   kid.css  —  与 gzh.css / science.css 同级，独立文件，避免污染主样式

   设计口径：
   1. 全部用 style.css 的 CSS 变量（--primary/--text/--border/--radius…），
      跟随主站主题，不引入第二套色板。
   2. 「暖色调」只用于宝宝相关内容（头像圈、里程碑标签），主结构保持克制。
   3. 移动端优先：随手拍是核心场景，手机上必须能单手完成「选图→写字→保存」。
