{#
 # Shop Breadcrumb (Bootstrap 5 Override)
 #
 # Replaces WooCommerce's breadcrumb with Bootstrap 5 breadcrumb component.
 # Skipped when parent theme is wrapping (wc-base.html.twig handles breadcrumbs).
 #
 # Expected context (from WooCommerce woocommerce_breadcrumb()):
 #   breadcrumb  - Array of [label, url] tuples
 #   wrap_before - Opening HTML (ignored, we use Bootstrap markup)
 #   wrap_after  - Closing HTML (ignored)
 #   before      - Before each item (ignored)
 #   after       - After each item (ignored)
 #   delimiter   - Between items (ignored, Bootstrap uses CSS)
 #
 # WooCommerce PHP equivalent: global/breadcrumb.php
 #
 # @package WcBootstrap
 # @since 0.1.0
