/**
 * ST Cache - Nonce Refresh Handler
 * 
 * PROBLEM: Cached HTML içindeki nonce'ler expire olabilir
 * SOLUTION: Client-side JavaScript ile fresh nonce çek ve replace et
 * 
 * WordPress Security Best Practice:
 * - Nonce'ler 12-24 saat expire olur
 * - Cache 1 hafta tutulabilir
 * - Client-side refresh = SEO friendly + güvenli
 * 
 * PAGESPEED FIX: Script 'defer' ile yüklenir (non-blocking)
 * - DOMContentLoaded yerine immediate execution (defer zaten DOM hazır garanti eder)
 * - Kritik yol gecikmeleri azalır
 * 
 * @package STCache
 * @since 1.0.0
