/* ============================================
   TO ADD NEW PROJECTS:
   1. Find the HTML section labeled "Recent Projects Scroller"
   2. Copy one of the project-item blocks
   3. Update the date and description
   4. IMPORTANT: Add it to BOTH sets (content is duplicated for seamless looping)
   
   TO CUSTOMIZE SPEED:
   - Change "40s" in the scroll animation to make it faster (lower) or slower (higher)
