{{- /*
  partials/meta/json-ld.html — JSON-LD structured data (Schema.org)

  Emits one <script type="application/ld+json"> block per page.
  Uses dict → jsonify → safeHTML to avoid Hugo's JS-context escaping.

  Schema selection:
    Home page     → WebSite  (with SearchAction if params.search_url set)
    Docs pages    → TechArticle  (front matter: type = "docs")
    Dated pages   → Article
    Everything else → WebPage

  BreadcrumbList appended when .Ancestors is non-empty.

  Configure in hugo.toml:
    [params]
      author      = "Trentuna"           # publisher/author name
      logo        = "/images/logo.png"   # site logo for publisher
      search_url  = "/search/?q={q}"     # enables SearchAction on WebSite
