Side B makes functional changes to the vote flow: it passes the browser delegate separately instead of embedding it in DSL text, prevents incorrect fallback to all items when the sibling comparison pool has fewer than two items, removes the unnecessary swap control, and consistently renames the public route from `/vote/compare` to `/vote` across handlers and tests. Side A is almost entirely Clippy-driven cleanup and minor test fixes, with its only behavioral change being enabling one previously unannotated test; the rest are refactors, lint fixes, and dead-code allowances.
