/**
 * Consent Mode v2 bridge.
 *
 * Maps vTilt's 3-boolean consent (analytics / marketing / advertising) to
 * Google's 4-key Consent Mode v2 payload (ad_storage, ad_user_data,
 * ad_personalization, analytics_storage) and pushes it through gtag.
 *
 * Mapping (default):
 *   advertising -> ad_storage + ad_user_data + ad_personalization
 *   analytics   -> analytics_storage
 *   marketing is not sent to Google by default (it covers email/SMS, not ads).
 *
 * Admin UI may override individual keys (`consentOverride`) to hard-wire a
 * specific value regardless of user consent — useful for jurisdictions or
 * projects with fixed policies.
