2 * Jarallax initialization for Gullström & CO Bricks sites.
3 *
4 * Loaded deferred with "jarallax" declared as a dependency, so WordPress
5 * guarantees this runs after the library and neither script blocks first paint.
6 * Because the script is deferred, the DOM is already parsed when this executes.
