- seoFirstPageRedirect answers the unnumbered URL or null when the target
is the URL itself, so /mapa-strony/<group>/strona/1 no longer loops (L4 WR-01)
- SeoHtmlSitemapPage takes the segment from the site answer, else the build
option, else the param, and redirects only when the helper answers a target
- the module registers seo-sitemap-<locale> at seo.htmlSitemap.paths
(defaults pl /mapa-strony, en /sitemap) and seo-sitemap-group-<locale>
at <path>/:group (plus <path>/:group/<segment>/:page in the path form);
a path an app page already has stays the app's
- SeoHtmlSitemapPage (global, overridable): H1, an H2 per non-empty
group, categories nested, a large group's link to its group page,
sitemap.empty; group pages with a built trail, page suffix and
<SeoPagination>; 404 for an unknown group or a page past the last,
301 for ?page=1, 503 when the sitemap API fails
- GET /api/__seo__/sitemap proxies the sitemap plugin's HTML API (only
while the CMS has the HTML sitemap on for the locale)
- <SeoSitemapLink>: the footer link while the HTML sitemap is on
- L3 default styles
