/**
 * Motors Theme - Consolidated Design System
 * 
 * This file replaces ~3,000 lines of embedded CSS scattered across PHP templates.
 * 
 * INSTALLATION:
 *   1. Copy to: MOTORS-FINAL-COMPLETE-v104/assets/css/motors-design-system.css
 *   2. Add to functions.php:
 *      function motors_enqueue_design_system() {
 *          wp_enqueue_style('motors-design-system', 
 *              get_template_directory_uri() . '/assets/css/motors-design-system.css',
 *              array(), '104.0.0');
 *      }
 *      add_action('wp_enqueue_scripts', 'motors_enqueue_design_system');
 *   3. Gradually remove embedded <style> blocks from PHP templates
 *      as you verify each component still renders correctly.
 *
