/* ============================================================
   anime-vitality.v8.css — 二次元活力动效层（第八轮迭代 2026-10-08：趴桌待机×点站交互）
   v7 变更：仅替换角色形象与版本号，样式规则与 v6 一致；
   · 13 位 AI 伙伴换成中文社区流行拟人形象（DeepSeek 蓝色女仆大鱼、
     ChatGPT 白龙娘、Grok 小魅魔……），每位一张独立透明 webp。
   · 页脚由“两张拼图 + 对齐窗口”改为“每位伙伴一个按钮 + 一张独立图”，
     彻底移除了 v5 的窗口/分身/克隆样式，残影机制从根上不存在。
   · 卡片头像（.ai-portrait-crop）与小圆头像（.companion-portrait）
     改为直接适配独立角色图（整身顶部构图 / 脸部特写图）。
   保留：单一角色鼠标指针（少女 + 魔杖）、樱花、点击星星、
         微交互、入场动效、打字机台词、悄悄话、头顶符号。
   全部效果均：
   · 仅在 <html> 拥有 av-on 时启用（JS 按 localStorage 开关控制）
   · 呼吸浮动与互动动作仅在 <html> 拥有 av-friends 时启用
   · 尊重 prefers-reduced-motion 与站内 site-reduced-motion 偏好
