/**
 * Unified Product Purchase Box Styles
 *
 * This CSS handles the responsive positioning of the unified purchase box
 * to eliminate CLS (Cumulative Layout Shift) caused by duplicate DOM elements.
 *
 * Strategy:
 * - Mobile (<900px): Inline, sticky position for easy access
 * - Desktop (>=900px): Sidebar, floated right
