Side A fixes a real correctness bug (duplicate `#entity-section`/`#entity-panel` IDs breaking morph targeting when multiple entity cards appear on the same page, e.g. vote compare) by switching to a per-item data-attribute selector, and it deduplicates significant logic by making vote_compare_item_card reuse entity_section instead of a parallel hand-rolled renderer. Side B is a smaller, well-tested UI tweak that changes sibling grouping semantics but has narrower impact and no bug being fixed.
