/* ========================================
   BACKGROUND IMAGES CONFIGURATION
   ======================================== */

/* QUICK START GUIDE:

   1. Add your background images to the 'images' folder
   2. Uncomment the section you want below
   3. Replace the filename with your actual image name
   4. Optionally add an overlay for better text readability

   EXAMPLE - To add background to About section:

   .about-bg {
       background-image: url('images/about-bg.jpg');  // Remove comment marks
       background-size: cover;
       background-position: center;
       background-attachment: fixed;
   }

   Then add overlay by uncommenting in .about::before or .section-overlay-light
