* What it does:
* 1. On load, reads gclid + utm_* from the URL and stores them in a
* first-party cookie for 90 days (only overwrites gclid when a new one
* is present, so a later organic visit does not wipe the paid click).
* 2. Appends those params to every calendly.com link and to any inline
* Calendly embed, so a completed booking carries them into Calendly and
* onward to the RedRain integration.
