+ * 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.
