Enhanced the FacetedSearch user interface by removing unnecessary bullet-point styling, creating a more integrated experience. Improved system robustness by implementing graceful handling of no-data scenarios, returning empty strings instead of errors. Maintained clear commit traceability and cross-repository consistency, contributing to a more cohesive and stable user experience across extensions.
