+      # the documented destructive boundary (not run in CI) and the DataTable rows are client-side JS. The
+      # achievable ceiling dropped to ~71.5%, so 72 sat above it and reddened main. 71 restores a true floor
+      # (still catches real regressions); ratchet back up as that code gets harness coverage.
