January 2025 performance summary focusing on delivering routing robustness and UI stability across two repositories. Implemented a routing improvement to prioritize route name matching for createRouteURL, with a deprecation path for path-based matching to guide migration and enhance routing accuracy. Migrated PrometheusNotFoundBanner styling from Material-UI makeStyles to the MUI v5 styled API to resolve runtime errors, updating related skeleton box and dismiss button styling. These changes reduce misrouting, stabilize the UI, and lay groundwork for easier future migrations and maintainability across headlamp-k8s/headlamp and headlamp-k8s/plugins.
