{#
  SEO and AEO head additions for cMCP.

  1. <title>: Material appends " - site_name" to every page title, so the home
     page read "cMCP: ... - cMCP" and titles that already name cMCP repeated it.
     The home page uses its front-matter title alone, and other pages drop the
     suffix when the title already contains the site name.

  2. Open Graph and Twitter card meta, with og:title equal to <title>.

  3. JSON-LD: one Organization node under the hub's @id, so every AgenTrust
     site names the same organization; a WebSite; a WebPage (home) or
     TechArticle (inner page) carrying this page's own title, description and
     canonical URL; a BreadcrumbList on inner pages; and the project node on
     the home page.

  Per-page meta descriptions come from hooks/seo.py. Canonical and description
  tags are emitted by Material when site_url is set.
