/**
 * Memories CSS - Wall of Memories Styling
 * 
 * UNIFIED SCROLLING APPROACH:
 * - Main container (.memory-lightbox-content) handles all scrolling
 * - Info section (.memory-lightbox-info) has no individual scrollbar
 * - Single scrollbar on main container for better user experience
 * - Content flows as one cohesive unit rather than separate sections
 * 
 * This prevents the bad UX of having multiple scrollbars and ensures
 * users can scroll through the entire modal content seamlessly.
