1/**
2 * @file
3 * Defines onloadTurnstileCallback placeholder before Cloudflare script loads.
4 *
5 * Uses Object.defineProperty to prevent Zone.js from proxying the function.
6 * This script must load before the Cloudflare Turnstile script to handle the
7 * race condition where Cloudflare calls onloadTurnstileCallback before
8 * turnstile.ajax.js is loaded.
