Side B adds a genuinely new capability (pool-scoped voting across a parent's children, with query param handling, next-pair suggestion within a pool, and threading through post-success JS) touching multiple files with real logic changes. Side A is a smaller, more narrowly-scoped UI improvement (making pin icons clickable to unpin) that mainly adds a form/button and CSS tweaks plus updates a browser test, which is useful but less substantial in scope and design impact than B's feature addition.
