/**
 * Builds BreadcrumbList JSON-LD (schema.org) for a page's position in the site
 * hierarchy. Google can show breadcrumbs in the result (Dom › Usługi › Detailing)
 * and uses them to understand structure — a signal that helps navigational
 * results and sitelinks.
 *
 * Unlike Organization/WebSite (site-wide, root layout), breadcrumbs are
 * PER-PAGE — build them from the page's ancestry and emit on that page:
 *
 *   import { buildBreadcrumbJsonLd } from '@intecion/ipal-kit'
 *   const jsonLd = buildBreadcrumbJsonLd([
 *     { name: 'Strona główna', url: `${base}/pl` },
 *     { name: 'Usługi', url: `${base}/pl/uslugi` },
 *     { name: 'Detailing', url: `${base}/pl/uslugi/detailing` },
 *   ])
 *   <script type="application/ld+json" ... />
 *
 * The crumb data comes from the page's real position (parent pages / URL path),
 * NOT hardcoded. Derive it from the resolved route, not a static list.
 *
 * Returns null for an empty/single crumb list — a one-item breadcrumb isn't
 * meaningful and shouldn't be emitted.
