/**
 * Cookie Consent Configuration
 * Documentation: https://cookieconsent.orestbida.com/
 *
 * GDPR-Compliant Approach:
 * - Analytics scripts use type="text/plain" data-category="analytics"
 * - The library blocks all marked scripts until user consents
 * - Scripts NEVER run until explicit consent is given
 * - Google Consent Mode is used for Google Analytics privacy mode before consent
 * - Other analytics (Cronitor, Pirsch, OpenPanel) are blocked until consent given
 *
 * Supported Analytics Providers:
 * - Cronitor RUM
 * - Google Analytics (GA4)
 * - OpenPanel Analytics
 * - Pirsch Analytics
