Side B implements a real, non-trivial UI/UX feature (clickable unpin from ranked child groups) with coordinated changes across markup, CSS themes, and an updated browser test covering the new flow, delivering tangible user-facing value. Side A is a small, well-tested bugfix (skipping pinned Reddit posts) which is useful but narrower in scope and impact than B's cross-cutting feature work.
