Side A fixes a real bug (duplicate hardcoded #entity-section ids breaking morph targeting when multiple entities render) by introducing per-item selectors, and it deduplicates vote-card rendering by reusing entity_section instead of a separate ad-hoc markup path, trimming CSS accordingly. Side B is a valid but minor dead-code removal with a supporting test update, offering less lasting architectural benefit despite being clean and correct.

council reasoning
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.
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.

[047b82bd] Remove redundant zero-ratio guard from reducer. Zeros are already rejected at the DSL parser and browser handler; the guard in apply_vote was dead code. The negative clamping stays since add_edge_weight already skips weight-0 edges correctly. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
