/**
 * Compatibility with WooCommerce Mix and Match Products.
 *
 * Container lines are never re-priced by tiered pricing: the Mix and Match plugin owns the
 * container's price, and re-pricing it would charge the tier price on top of the contents.
 *
 * Child items (the products inside a container) are excluded by default. The "Apply tiered pricing
 * inside containers" setting lets tiered pricing discount them — only for containers with per-item
 * pricing, where every child line carries its own real price. Children of statically priced
 * containers always stay untouched.
