/**
* H4KI — Givecloud exit-intent popup suppressor
*
* Hides the "Are you sure you want to leave without making a difference?"
* modal that Givecloud's Giving Experience widget shows on exit intent.
*
* Detection is text-based (not class-based) because the widget is React +
* Tailwind and its utility classes can change between Givecloud releases.
*
* Works whether it's loaded:
* - inside a Givecloud-hosted page / the widget document itself
* (Givecloud admin custom script section), or
* - on the parent WordPress page (the embedded widget lives in a
* same-origin iframe, so page JS can reach into it).
*
* Last verified against widget markup: Jul 2026.
