/**
 * =====================================================================================
 * GLOBAL FOOTER STYLES
 * =====================================================================================
 * 
 * Complete styling for the NEW global footer component
 * CRITICAL: This is completely independent from the sticky mobile footer (.bottom-nav)
 * 
 * STRUCTURE:
 *   - Row 1: Main content (4 columns: brand, main menu, secondary menu, contact)
 *   - Row 2: Social & communication links
 *   - Row 3: Copyright
 * 
 * RESPONSIVE:
 *   - Desktop: Full 4-column layout
 *   - Tablet: 2-column layout
 *   - Mobile: Single column stack
 * 
 * NO INTERFERENCE: This footer does not touch or modify .bottom-nav styles
 * =====================================================================================
