Custom Cursor Follower

Create a custom cursor follower. The default cursor should be hidden. A small circle follows the mouse with slight lag (lerp). When hovering over buttons or links, the cursor expands and snaps magnetically toward the element center. Use React state to track mouse position and requestAnimationFrame for smooth interpolation. Use Tailwind CSS. Keep the cursor subtle—white outline on dark background. Add a few large text links and buttons as demo targets.

创建一个自定义光标跟随器。默认光标隐藏。一个小圆圈带轻微滞后（lerp）跟随鼠标。悬停在按钮或链接上时，光标放大并磁性吸附到元素中心。使用 React state 跟踪鼠标位置，requestAnimationFrame 实现平滑插值。使用 Tailwind CSS。光标保持微妙——深色背景上的白色轮廓。添加几个大文本链接和按钮作为演示目标。
