Side A is a focused, well-explained fix that replaces awkward redirect-based auth flow with in-place HTML fragment responses, consolidates layout code, and adds matching CSS — a clear, self-contained improvement. Side B, despite being labeled 'fix', bundles unrelated concerns (new dependencies, Cargo.lock churn, a new vote-compare feature, typed form-hole parsing, JS slider logic) into one vague commit, making it harder to evaluate as a coherent, necessary change even though it includes some useful tests.
