/* 
 * Enhanced Blob Animations with Customizable Parameters
 * 
 * To adjust blob movement:
 * - Change translate values for distance (current: 30-50px)
 * - Change scale values for size variation (current: 0.9-1.1)
 * - Adjust animation duration in .animate-blob (current: 7s)
 * 
 * To make blobs more prominent:
 * - Increase opacity in HTML (current: opacity-40 dark:opacity-30)
 * - Increase blur-2xl to blur-3xl in HTML for softer edges
 * - Increase w-96 h-96 sizes in HTML (try w-[32rem] h-[32rem])
