/**
 * Nexa Light Settings Modal Styles
 *
 * Extends app-settings-modal.css with Nexa-specific styling
 *
 * Ergonomic Improvements (2026-03-22):
 * - Fixed scrolling issues in content area with proper flex/overflow handling
 * - Increased padding and spacing throughout for better readability
 * - Enhanced visual hierarchy with improved typography and sizing
 * - Better hover states and transitions for interactive elements
 * - Improved form fields with larger hit areas and better focus states
 * - All scrollable areas now have proper min-height: 0 for flex shrinking
 */
