2// KIRA RESEARCH — /js/track.js
3// First-party funnel events for /en/admin/funnel. Privacy by construction:
4//   - no cookies, no IP, no email: only a random per-tab id (sessionStorage) + path + coarse source
5//   - respects Do Not Track; does nothing on admin, studio, previews and localhost
6// Events: pageview (on load), search (library search with 3+ letters, once per query),
7//         request_email / waitlist / lead (a successful form POST) — all detected by watching
8//         fetch, so no form on the site needs to be edited.
