When the user token size exceeds the browser's cookie size limit (e.g., when the user is a member of many groups), the token is split across multiple cookies to ensure proper authentication.

External tools outside of KKP (e.g., Kubernetes Dashboard, Grafana, Prometheus) are not supported with multi-cookie tokens.
