 *    - Perfect for hero sections, banners, colored backgrounds
 *    - Example: <div class="container-fluid" style="background-color: var(--primary-color);">
 * 
 * 2. .container-wide - Use for main content sections
 *    - Max-width: 1360px with centered margins
 *    - Responsive padding on mobile/tablet
 *    - Perfect for main page content, wide layouts
 *    - Example: <div class="container-wide">
 * 
 * 3. .container-narrow - Use for focused content
 *    - Max-width: 960px with centered margins  
 *    - Responsive padding on mobile/tablet
