/* 特色自定义光标：知识图谱 / 多题归纳 / 深度回忆 三页全局生效。
   分层设计：
   1) body 定义 + `* inherit` 继承链：页面内所有元素默认特色光标；
   2) 画布容器/卡片层用 :not(#kg-cursor-anchor) 提升到 (1,2,1)!important，
      压过历史 !important 规则（如 .stage.pointer-edit-mode 的 default、
      knowledge-recall-p4322 的 .kr-viewport default——该"左键保持箭头"的
      旧决策已按产品要求改为特色光标）；
   3) 交互态（拖拽 grabbing、绘画 crosshair、平移 grab）以同等权重声明在后，
      保证操作反馈不被特色光标吃掉；
   4) 按钮/链接 pointer、文本输入 text 等系统惯例由继承链后的规则恢复。 */
