背景光束区域

Create a dark section with animated diagonal light beams crossing behind centered content. Use several thin, slightly blurred lines at varying angles and opacities, animating them to slowly drift or pulse. The beams should be subtle—white/blue at low opacity so they add depth without distracting. Center a bold headline and short paragraph over the beams. Use Tailwind CSS and CSS keyframes. No images.

创建一个深色区域，中央内容后方有对角动画光束交叉穿过。使用多条不同角度和透明度的细线，略带模糊，缓慢漂移或脉冲动画。光束应微妙——低透明度的白/蓝色，增加深度而不分散注意力。在光束上方居中放置粗体标题和短段落。使用 Tailwind CSS 和 CSS keyframes。无图片。
