自定义光标跟随器

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.
