/**
* GEOGRAPHIC ACCESS RESTRICTION
*
* This segment of code is designed to restrict access to the website based on the geographic location of the user.
* It checks the server API to ensure that the geographic checks are only applied in web contexts, not CLI or FPM.
* Allowed countries are defined in the $allowedCountries array. Requests from other countries are blocked with a 404 response.
*
* Dependencies: Requires server variables set by the GeoIP module.
