1/**
2 * Kantan Analytics — form session field injector.
3 *
4 * Adds hidden kantan_session_id / kantan_visitor_id inputs to every form on the
5 * page so form-plugin submissions can be attributed to the visitor's session.
6 * IDs come from the tracking script's sessionStorage/localStorage; if neither is
7 * present (e.g. logged-in admins, who aren't tracked) the script no-ops.
