/* Design Tokens and CSS Variables */
/*
 * IMPORTANT: CSS Specificity Management
 *
 * This file contains global design tokens and component styles.
 * To prevent conflicts with application-specific styles:
 *
 * 1. Component styles are scoped to specific containers (.dg-demo, .progress-demo)
 * 2. Step progress styles only apply within .step-progress containers
 * 3. Generic class names like .btn, .step-content are scoped to avoid conflicts
 * 4. Utility classes use standard Tailwind naming conventions
 *
 * When adding new component styles, always scope them to prevent conflicts!
