Side A makes a functional design improvement by replacing a global `#entity-section` target with per-item `data-entity-section` selectors and a shared `entity_section_selector`, allowing SSE/Idiomorph updates to address the correct entity section. It also refactors vote comparison to reuse the common `entity_section` rendering, eliminating duplicated UI code and aligning styling, whereas Side B mainly removes a now-redundant guard and updates tests to reflect existing behavior around zero-weight edges.
