No. The front-end is a single small script and stylesheet with no third-party libraries, and leads are written to their own indexed table rather than as posts, so even a busy campaign does not weigh your site down. The popup's stylesheet does not hold up the page: it is fetched in the background and the launcher appears once it is in. The popup itself is not laid out, and its wheel not drawn, until a shopper opens it. In your dashboard, the media library and the colour picker are loaded only on the Wheel screen, which is the one that uses them. Google's reCAPTCHA and a Google font, if you use them, are only fetched when a visitor opens the wheel, not on every page it could open on. The Your prize reminder adds a small script to each page, under 600 bytes once compressed, which looks for a won code in the browser; its own script and stylesheet are fetched only by a shopper who has one. The cart page and the checkout each get a script of their own, under a kilobyte once compressed, which notes the codes in the cart.
