window screen resize listener (detect response mode)

Step 1

        }

        if (windowWidth <= 2048) {
            return 'large';
        }

        if (windowWidth > 2048) {
            return 'extra large';
        }

        return '';
    }

    Alpine.store('windowWidth', window.innerWidth);
    Alpine.store('windowHeight', window.innerHeight);
    Alpine.store('screenType', screenType(window.innerWidth));
