/* ============================================================
 * 安安网页 v1.2 排练场 - 全屏桌面伴侣界面（无样机框版）
 * ------------------------------------------------------------
 * 目标：整页即"成品数字伙伴界面"——立绘当主角，UI 浮于虚化背景之上
 * 分区（100dvh 全屏自适应，零页面滚动）：
 *   顶栏玻璃状态条 → 主区（左·立绘大舞台 + 右·伴侣面板） → 精简 ANAN OS 底栏
 * 美学：暗色暖调 + 毛玻璃 backdrop-filter + 圆角卡片 + 柔和阴影 + 呼吸辉光
 * 约束：纯静态、相对引用、零明文；kiosk 一屏容纳零滚动
 * JS 契约（不可改名）：#anan-figure/.blink、#bubble/.show、.tap-hint/.hide、
 *   .mood-btn/.on、#mood-auto/.off/.spinning、.st-mood、[data-mood]、#l2d-canvas
 * 动画契约：breathe / blinkAnim / talkPulse / spin / msgIn / moodGlow
