- post, index, category, tag and author pages render <SeoBreadcrumbs> at the top of their content while journal.breadcrumbs is on (default); false leaves the trail to the site's layout, the BreadcrumbList data is unchanged - JournalPagination renders <SeoPagination class-prefix="journal-pagination"> with the journal's labels: the same class names, plus page 1, the last page, gap items, aria labels and head rel prev/next, with links in the CMS's pagination form - with vue-seo-layer's seo.pagination.form 'path' the module registers <listing>/<segment>/:page routes (journalPagedRoutes), and the listing pages read the page from the :page param or ?page (pageFromRoute) - the category pillar text renders on page 1 only, the description on every page; an h1 in it becomes h2 while the category row's content_h1_to_h2 is on (absent counts as on)
