{#
  SEO and AEO head additions for the TRACE docs.

  Title: Material appends " - TRACE" to every page title, which repeated the
  site name ("TRACE v0.2 - TRACE"). The home page now uses its front-matter
  title alone, and a title that already names the site gets no suffix. Open
  Graph and Twitter use the same title string.

  JSON-LD: one AgenTrust Organization node under the hub's @id, the WebSite,
  and a node for the page itself (WebPage on the home page, TechArticle
  elsewhere) carrying its own title, description and canonical URL. Inner pages
  add a BreadcrumbList; the home page adds the SoftwareApplication node for the
  agentrust-trace library. Page descriptions come from hooks/seo.py when the
  front matter has none. Material already emits the canonical link.
