    screen.orientation.lock('portrait').then(function() {
        console.log('Screen orientation locked to portrait.');
    }).catch(function(error) {
        console.error('Screen orientation lock failed: ', error);
    });

            console.error(`${err.name}, ${err.message}`);
        }
    };

    requestWakeLock();
}

window.addEventListener('beforeunload', () => {
    if (wakeLock && wakeLock.active) {
        wakeLock.release().then(() => {
