/*
 * Custom styles for MyWebApp
 * -----------------------------------------------------------
 * This stylesheet replaces Tailwind CSS and implements all styling
 * including custom colors, responsiveness, and component styles.
 *
 * FIX: Added 'appearance: none' to the submit button to remove
 * native browser styling and ensure a modern look.
 * ENHANCEMENT: Added styles for home.html (.hero-section) and
 * legal.html (.legal-document) pages.
