/* =====================================================================
   小账喵 AI 助手角色系统 v1.0 —— 样式
   设计约束：
   - 角色本体默认隐藏；右缘「探头浮标」为悬浮入口，点击后小猫滑入 + 面板展开
   - 展开后角色：position:fixed; right:24px; bottom:100px; z-index:999
   - 尺寸：手机 64-80px（默认 76）/ PC 80-96px（默认 88），断点 768px
   - 动画：idle 呼吸 scale 1→1.05→1 周期 3s；drowsy/sleep 慢呼吸；动作切换用弹入
   - 只消费主题 token（--card-bg/--text-*），不承担任何主题装饰职责
