  _includes/head/custom.html — REVISED FOR UCF.
  Replaces the earlier version, which asserted a Rutgers affiliation.

  Verify the hook exists before relying on this:
      grep -n "head/custom" _includes/head.html

  _includes/seo.html already emits a Person node with `sameAs` from the
  `social:` block. This adds only what seo.html cannot express: the group as
  an organization, and the UCF affiliation. Do not add a second Person node.
