 * ==========================================================================
 * COLOR CUSTOMIZATION GUIDE
 * ==========================================================================
 * 
 * To change the primary color (currently #041052):
 * 1. Update --event-primary-color in :root
 * 2. Generate new icon filter at: https://codepen.io/sosuke/pen/Pjoqqp
 * 3. Update --event-icon-filter with the generated filter
 * 
 * Example for blue (#0066cc):
 * --event-primary-color: #0066cc;
 * --event-icon-filter: invert(27%) sepia(96%) saturate(1332%) hue-rotate(200deg) brightness(99%) contrast(101%);
 *
