1/**
2 * Dynatrace Cookie Consent Handler (Common)
3 * Version: 3
4 *
5 * Integrates Dynatrace RUM with TrustArc consent manager.
6 * Enables/disables Dynatrace tracking based on user's Performance cookie consent.
7 * Uses separate TrustArc identifiers for cookie parsing and API-based consent checks.
8 *
9 * Shared across all MSI storefronts:
10 * - Classic (OCC Storefront)
11 * - B2P/B2B (OSF - Oracle Storefront Framework)
12 * - B2C (OSF - Oracle Storefront Framework)
