动画1
主要功能：
真实的发射轨迹 - 烟花从底部发射到指定位置
物理引擎效果 - 包含重力、摩擦力、缓动函数
多彩爆炸效果 - 多种颜色的粒子爆炸
渐变消失 - 粒子逐渐变淡并缩小
交互控制 - 点击、按钮控制等多种方式
技术亮点：
面向对象设计 - 使用ES6类封装烟花逻辑
高性能渲染 - 使用requestAnimationFrame优化动画
真实物理模拟 - 重力、速度、摩擦力计算
视觉效果增强 - 发光效果、缩放动画、透明度变化
响应式设计 - 适配不同屏幕尺寸
控制方式：
点击屏幕 - 在点击位置发射烟花
发射烟花按钮 - 随机位置发射
自动发射按钮 - 开启连续发射模式
停止发射按钮 - 停止自动发射
清空画面按钮 - 清除所有烟花效果
烟花效果包括发射轨迹、爆炸粒子、重力下落、渐变消失等真实物理效果，营造出高质量的视觉体验。
