{{--
    The breadcrumb trail — docs/wireframes-v12/view-project.html's
    `.breadcrumb-nav`: links separated by a "/" span, the last item plain text.

    Usage, from inside a view that extends layouts.app:

        @section('breadcrumbs')
            <x-breadcrumbs :items="['Projects' => route('projects.index'), 'Add Project' => null]" />
        @endsection

    A null url renders the label as plain text (the current page).

    ---
    CR-2 (spec §12). v12 puts the trail in the header, beside the page title,
    not at the top of the content — so this now renders into the
    `breadcrumbs` section that layouts/partials/topbar.blade.php yields.
    Sections declared by a view are captured before its layout renders, which
    is why a component in the content file can end up in the header.

    A page that declares no such section (the dashboard, matching index.html)
    gets a Home-only trail from the topbar instead; this component is not
    involved in that case.

    Separator: v12 writes a literal "/" in a `.sep` span rather than the chevron
    icon the v10 pack used. Kept as text, and aria-hidden, so a screen reader
    reads "Projects, Add Project" and not "Projects slash Add Project".

{{-- Only the LAST crumb may claim to be the current page. A trail can legally
     carry more than one url-less item — CR-7's two listings both render
     "Home / Administration / <page>", where Administration is a sidebar section
     with no screen of its own, exactly as the wireframe writes it — and two
     elements answering to aria-current="page" is one more current page than a
     document can have.

     "Last" is asked positionally, with $loop->last, and not by comparing the
     label against array_key_last(): the labels ARE the array keys, so a trail
     that legitimately repeats one ("Projects / … / Projects") would have marked
     both. Position is the question being asked, so position is what is
     compared. --}}

                 inside an attribute list leaves its own whitespace behind, and
                 the component's tests match the tag exactly. --}}
