/**
 * Demand Level Selector Component Styles
 *
 * Styling for the physical demand level comparison interface with:
 * - Color-coded rows (green to red gradient)
 * - Clear visual hierarchy
 * - Full dark/light mode support
 * - Responsive design
 *
 * NOTE: This component uses the centralized color management system from src/color-system/colors.css
 * All colors are referenced using CSS custom properties (variables) for consistency.
