/*
 * NAS Prototype Design System — Global CSS
 *
 * Purpose:
 *  1. Import NAS-approved web fonts (Arial is system-installed; this file adds
 *     any additional weights via system-font fallback + optional web-font CDN).
 *  2. Provide Kentico-specific resets so prototype styles don't bleed into or
 *     be overridden by Kentico's base stylesheet.
 *  3. Define global layout utilities that can't be expressed as Tailwind classes.
 *
 * Loaded via <link rel="stylesheet" href="global.css"> in index.html.

 *
 * In the local dashboard (index.html) the same class is added automatically by
 * the loader, giving consistent results in both environments.
