/*
 * "Ways to buy" (template-parts/blocks/product/commerce-channels.php) had
 * zero CSS coverage anywhere in the repository -- .offer-grid, .offer-card,
 * .offer-intelligence__*, and .button.button-primary all matched no rule,
 * so retailer/price/history data rendered as an unstyled text dump. This
 * is the product page's commerce decision surface (Package 94 priority
 * tier: identity > certifications > safety > commerce/offers), so it gets
 * a real card treatment reusing the same tokens as the rest of the
 * product-detail system rather than a one-off style.
