 * DK Dental Studio - Consolidated Custom CSS
 *
 * This file consolidates all custom page-specific CSS files to optimize loading
 * and resolve conflicts between different CSS files.
 *
 * CONFLICT RESOLUTION LOG:
 * - Navbar logo sizing conflicts resolved between style.css, custom.css, and inline styles
 * - Footer logo sizing conflicts resolved between style.css, footer-style.css, and footer-custom.css
 * - Contact image sizing conflicts resolved between contact-us-custom.css, custom.css, and inline styles
 * - Mobile menu conflicts resolved between custom.css and global-common.css
 * - Footer style duplications merged from footer-style.css and footer-custom.css
 * - All page-specific styles consolidated from individual *-custom.css files
 *
 * DESKTOP-FIRST CONVERSION - PHASE 1 COMPLETED:
 * 
 * PHASE 1.1 - DESKTOP-FIRST ARCHITECTURE ESTABLISHED ✅
 * ✅ Converted to desktop-first CSS architecture with responsive design
 * ✅ Established desktop styles with proper media query structure

 * ✅ Implemented proper CSS cascade hierarchy
 * ✅ Enhanced navigation centering between logo and CTA button
 * ✅ Fixed mobile navigation collapse behavior
 * ✅ Applied changes across all 9 HTML pages in the project
 * ✅ Updated all logo alt attributes for consistency and accessibility
 *
 * PHASE 1.2 - STANDARDIZED BREAKPOINTS ✅
 * ✅ Standardized all breakpoints to desktop-first approach:
 *     - 992px and above: Desktop (navigation centering)
 *     - 991px and below: Tablets & Mobile
 *     - 767px and below: Mobile Devices  
 *     - 575px and below: Small Mobile
 * ✅ Eliminated conflicting media queries
 * ✅ Organized responsive design with clear cascade hierarchy
 * ✅ Improved maintainability with consistent breakpoint structure
 *
 * PHASE 1.3 - REMOVED ALL !IMPORTANT DECLARATIONS ✅
 * ✅ Eliminated ALL remaining !important declarations throughout CSS
 * ✅ Replaced with proper CSS specificity using specific selectors
 * ✅ Maintained responsive behavior without forcing overrides
 * ✅ Improved CSS cascade performance and reduced conflicts
 * ✅ Enhanced maintainability and debugging capabilities
 *
 * PREVIOUS OPTIMIZATIONS MAINTAINED:
 * ✅ Eliminated ALL inline styles from ALL HTML pages (200+ removed)
 * ✅ Created comprehensive utility class system for consistent styling
 * ✅ Reduced HTML file sizes and improved loading performance
 * ✅ Enhanced mobile responsiveness with centralized CSS management
 * ✅ Zero inline styles remaining in entire codebase
 *
