/*
 * WooCommerce related-products and upsell recommendations
 *
 * The .ch-recs class is added at runtime by woocommerce-recommendations.js
 * to both .related.products and .up-sells.upsells.products on the single
 * product surface. Styling against this single class lets the rules sit
 * at low specificity (0,2,0–0,3,1) and rely on the child stylesheet's
 * source order — which loads after WooCommerce's own CSS — to win.
 *
 * Previous rules used five-segment compound selectors to escalate
 * specificity. That pattern compounds across maintenance cycles. Anyone
 * adding new behavior to this surface should keep selectors anchored on
 * .ch-recs and resist deeper chaining.
