/**
 * Bitstech Store — Single Product Layout Variants
 *
 * Three real layout reflows controlled by `bt_product_layout` Customizer setting:
 *   • default   — WooCommerce 50/50 split (gallery left, summary right)
 *   • extended  — Full-width hero gallery on top, summary in centered column below
 *   • fullwidth — 60/40 split with sticky gallery, container expanded to 1600px
 */

/* ═══════════════ DEFAULT LAYOUT ═══════════════
   No overrides — uses WooCommerce template defaults. */

/* ═══════════════ EXTENDED LAYOUT ═══════════════
   Hero-style: gallery occupies full width as a wide showcase, then the
   product summary appears below in a centered, readable column. Best for
   visual products (electronics, fashion, gear). */
