/* aikc-typing-r1.css —— 打字训练营 50 关（r17-3 / r17-5 UI 重做）
 *
 * 设计策略：本脚本刻意复用原生 class 名（.typing-level-grid / .typing-target /
 * .typing-workbench / .typing-dashboard / .typing-current-level / .typing-set-tabs），
 * 因此绝大部分样式直接继承站点既有 CSS。这里只补：
 *   ① 新增元素（页签内 strong/small、状态条、操作按钮、空态）
 *   ② r17-5 工作台 UI：字符舞台 + 逐字符高亮 + 隐藏输入框 + 进度条 + 失焦遮罩
 *   ③ 无障碍与减弱动效
 */
