/*
 * Product page redesign. All rules are contained by .product-page so the
 * existing site header, breadcrumbs and footer keep their own styles.
 *
 * The product script measures the fixed site header and product summary bar:
 *   --site-header-offset: visible fixed header height, or 0px
 *   --product-bar-height: current product summary bar height
 * Keep .gallery and .configuration in the same .product-layout grid so the
 * photograph stops sticking when the configuration column ends.
