 * Loads Google Analytics — GTM if a container ID is set, otherwise GA4 gtag.
 *
 * Consent Mode is initialised to the visitor's stored consent BEFORE the tag
 * loads (via setDefaultConsent from the consent module), so tags respect the
 * choice from the first hit; useConsent sends an update the moment the visitor
 * decides. IDs are public and come from SiteIntegrations, passed in as props
 * (the client project reads them server-side).
 *
 * Renders nothing — it only injects the scripts. Mount once, high in the tree
 * (e.g. root layout), inside ConsentProvider.
