/**
 * GAH QR Card — page styles
 *
 * Design: Clean, focused, mobile-first.
 * The QR code is the star. Everything else supports it.
 *
 * When used as a shortcode inside a WordPress page, the theme
 * provides the header/footer. In PWA standalone mode (home screen),
 * JS adds .gah-qr-standalone to body to hide site chrome.
