~x-ai/grok-latest → A (4:1)

A replaces a single global #entity-section/#entity-panel id with per-item data-entity-section selectors and a shared entity_section_selector, then reuses entity_section in the vote compare UI and drops the duplicated vote-compare markup/CSS—real lasting UI structure. B only deletes a dead zero-ratio early-return in apply_vote and adjusts one test, a correct but tiny cleanup already covered by parser/handler guarantees.
