/**
 * Nam Việt — Product archive (Sản phẩm) — v2 industrial direction.
 *
 * Source: design/v2/products.html (inline <style> = spec). The shell (utility bar,
 * header, footer), base primitives (.container, .btn*, .kicker, .notch, .grid-bg,
 * section, .sec-head) and the shared inner-page hero band (.page-hero, .crumb)
 * come from base.css/header.css/footer.css — this sheet only adds the archive
 * sections. Class names keep the `nv-` prefix the archive shortcodes emit
 * (inc/template-helpers.php) so markup + styling stay in sync.
 *
 * Enqueued conditionally (handle `nv-products`) for the product post-type archive
 * + product_category taxonomy archive (inc/hooks-frontend.php).
