{{--
    Breadcrumb (PRD 4.21) — used on Portfolio detail, Blog detail, Contact and
    the legal pages.

    $items is an ordered array of ['label' => string, 'url' => ?string]. Home is
    prepended automatically so no caller has to remember it, and the final item
    is rendered as plain text with aria-current="page" rather than a link,
    because linking to the page you are already on is a WCAG annoyance
    (PRD 14.18).

    BreadcrumbList JSON-LD is emitted alongside the visual list so the two can
    never disagree about the trail (PRD 14.13).
