动态爱心树
1.柔和色彩方案：
主色调：柔粉色(#ffa7c4)和浅紫色(#f9f7fe)
背景：浅蓝色渐变(#f9f7fe到#e3f2fd)
文字：灰紫色(#5a5a7a)
2.动态效果：
分形算法生成的爱心树（每次生成形状都不同）
从树枝末端飘落的爱心动画
交互式控制面板可调整树形参数
悬停效果增强用户体验
3.视觉效果优化：
使用CSS渐变和阴影创造深度感
半透明玻璃态UI设计
爱心使用发光效果增强视觉吸引力
响应式设计适配各种屏幕尺寸
4.详细步骤说明：
5个实现步骤的详细解释
每个步骤有独立的卡片设计
步骤编号使用渐变圆形设计
5.交互功能：
生成新树按钮
添加爱心按钮
树枝角度调节滑块
树枝长度调节滑块
