using Unity.WebPlatform;

public class WebGameManager : MonoBehaviour 
{
    void Start() 
    {
        // Check if running in browser
        if (WebPlatform.IsBrowser) 
        {
            // Enable PWA features
            WebPlatform.EnablePWA(true);
            
            // Configure browser-specific settings
            WebPlatform.SetFullscreenMode(WebFullscreenMode.Viewport);
        }
    }
}
