 * @description Dashboard-specific layout and styling
 * @author      Mauricio Moreno Vásquez
 * @version     2.0.0
 *
 * This file handles:
 * - Dashboard page layout (wider than calculator pages)
 * - Header customization with user menu
 * - Welcome section styling
 * - Dashboard section spacing and typography
 * - Responsive design for mobile/tablet
 * - Loading and auth gate states
 * - Print styles
 *
 * Dependencies:
 * - design-system.css (CSS variables)
 * - components.css (base component styles)
 * - dashboard.js (injects component-specific styles dynamically)
 *
 * Note: Dashboard.js injects ~400 lines of component styles.
 * This file focuses on page layout, not component styling.
