/* ============================================================
 * NORMA NEWS — PWA Install Banner & Splash (pwa-install.css)
 * ------------------------------------------------------------
 * Aman untuk CSS website yang sudah ada:
 *   - HANYA memakai class berprefix .pwa-install-* / .pwa-splash-*
 *   - TIDAK ada selector global (button, body, div, dll.)
 *   - Mobile-first, responsif, ringan (~5 KB)
