/**
 * Inner page hero — product categories and single product pages.
 *
 * Visual language is the storefront's existing industrial layer (graphite
 * photo, Poppins display type, single action red, 5px card radius) so the two
 * conversion entry points no longer fall back to a bare white page.
 *
 * Component-scoped tokens live in the :root block below; brand colour and
 * radius are consumed from the industrial B2B token set
 * (--fcdc-b2b-red / --fcdc-b2b-red-dark / --fcdc-b2b-radius).
 *
 * Contrast (measured on the prototype, plate sampling per text node):
 * eyebrow 6.18–7.15, H1 4.98–15.78, lead 9.83–11.38, badge 12.59–14.01,
 * ghost CTA 11.24–12.89, primary CTA on #d62b27 = 4.96 — all above
 * 4.5:1 (3:1 for the large H1).
 *
 * @package Weline_Motor
 * @version 1.0.0
