Explain zero-score and tied recommendations

A product ranked first with score 0, or tied with every alternative, is not meaningfully preferred. The interface should say “No supporting-profile differentiation” rather than implying a winner.

No files or tests are named in the issue, so first locate where recommendation results and ranking labels are rendered in the UI and where score-based copy is chosen. Trace how zero-score and tie cases are handled, then change that winner text path to show the exact phrase “No supporting-profile differentiation”. After updating the relevant UI/string rendering path, run the project’s recommendation/display test suite or related frontend tests to confirm wording expectations.
