/* =============================================================================
 * XEGORA Configurator Xerox - Wizard Step 2 (Configure)
 *
 * Mobile-first stylesheet for the configure step. Sticky header (back +
 * product name + progress) and sticky footer (single Continue button) stay
 * pinned <768px; from 768px upward both unstick and the Continue button is
 * repositioned via CSS only (no JS move).
 *
 * Scope: every selector lives under .xcx-step-2.
 * Variables: reused from wizard-base.css (no redeclaration).
 *
 * @package XegoraConfiguratorXerox
