// cinny-desktop #19: Windows smoke test against the INSTALLED app.
//
// The app is started with WebView2's DevTools port open
// (WEBVIEW2_ADDITIONAL_BROWSER_ARGUMENTS=--remote-debugging-port=9222) and this
// script drives its real page over CDP with playwright-core. No login: every
// check runs on the login screen or through the app's own Tauri commands.
//
//   node scripts/windows-smoke.mjs <outDir>
//
// Checks whose feature isn't in the build under test are reported "n/a"
// instead of failing, so the same script runs on main and on PR branches.
