/* ============ 彩纸礼花（仅合格时播放）============
   两台虚拟炮口固定在屏幕左右下角，向斜上方喷射纸片。

   物理模型（而不是固定 easing）：
   - 上升阶段受重力减速：位移曲线 concave down，越接近顶点越慢
   - 顶点附近速度接近 0，会有一个明显的"悬停"瞬间
   - 下落阶段重力加速：越落越快，曲线 concave up
   - 水平方向近似匀速（纸片很轻，水平速度衰减慢）
   - 另有一层 cf-sway 动画让纸片左右飘摆，模拟空气阻力下的横向摆动
   做法：位移用多个关键帧，每帧自带 animation-timing-function，
