关键改动说明 #

• 动态文字颜色：利用background-clip: text让H1文字颜色跟随渐变背景变化，替代手动拆分文字加span的硬编码方式，实现屏幕缩小时重叠区域自动变白。
• 响应式适配：
  • 用clamp()设置H1字体大小，随屏幕宽度自动缩放，避免溢出。
  • 媒体查询分阶段调整渐变遮罩的白色占比，同步匹配文字颜色渐变，保证视觉一致性。
• 小屏优化：屏幕足够小时，遮罩层切换为全白色背景，文字变回纯黑色，确保内容完全清晰显示在容器内，同时缩减上下内边距、缩小字间距提升移动端体验。
• 布局稳定性：添加overflow: hidden防止内容溢出，给容器加左右内边距避免文字贴边。
