1/**
2 * HomeRunner Toolkit — AI Booking Channel landing capture.
3 *
4 * Runs on every front-end page (including page-cached ones, which is why capture
5 * is client-side: FlyWP nginx caches ignoring Set-Cookie, so a server set on a
6 * cached landing is unreliable). Vanilla, no dependencies.
7 *
8 * Three first-touch paths, all writing a 30-day cookie only when none exists:
9 *   1. hr_src=<accepted tag> in the URL -> cookie "<tag>|<epoch-ms>", then
10 *      clean the URL. An unknown tag value is ignored as a tag and path 2 runs.
11 *   2. no cookie + an AI-referrer document.referrer (exact host or dot-suffix)
12 *      -> cookie "ref:<base-domain>|<epoch-ms>" and a one-shot sendBeacon.
13 *   3. window.hrtkAicCapture(<script source>) -> cookie "<source>|<epoch-ms>".
14 *      Defined at script evaluation, so a first-party script can call it
15 *      before DOMContentLoaded.
16 *
17 * On checkout, it copies the cookie into the hidden hrtk_aic_src field and moves
18 * it into the serialized checkout form so the server can read it same-request.
