🛠️ Refactor suggestion

Consider optimizing banner rendering performance.

While the implementation is functionally correct, the rendering of multiple banners might contribute to the low performance score (46) in the Lighthouse report. Consider these optimizations:

  1. Implement lazy loading for inactive banners
  2. Use CSS transforms for transitions instead of mounting/unmounting

Here's a suggested optimization:

 <div className='relative flex min-h-72 w-full items-center justify-center overflow-hidden lg:h-[17rem] lg:w-[38rem]'>
-  {visibleBanners.map((banner, index) => (
+  {visibleBanners.map((banner, index) => {
+    // Only render active banner and immediate neighbors
+    const isVisible = Math.abs(index - (activeIndex % numberOfVisibleBanners)) <= 1;
+    if (!isVisible) return null;
+    return (
       <Banner
         key={index}
         title={banner.title}
         dateLocation={banner.dateLocation}
         cfaText={banner.cfaText}
         eventName={banner.eventName}
         cfpDeadline={banner.cfpDeadline}
         link={banner.link}
         city={banner.city}
         activeBanner={index === activeIndex % numberOfVisibleBanners}
         className={className}
         small={small}
       />
-    ))}
+    );
+  })}
