Side A fixes real bugs in test infrastructure (wrong regex-vs-string split arg, wrong response body length causing broken redirects, wrong stream method, unguarded nil token) plus adds exception handling and CSS-selector-based readers, unblocking a broken E2E auth suite. Side B is a smaller, self-contained UI refinement (min-max normalization for rank coloring) that's well-tested but lower-impact and more cosmetic than a functional bugfix.
