Side B adds a substantive new capability: pool-scoped voting, including `pool` query handling, automatic pair selection from a parent's children, preservation of pool context across vote navigation, and UI entry points ('vote on children'). Side A primarily refactors the DSL syntax by moving vote explanations before comparisons and updates the parser, documentation, fixtures, and tests to enforce that new format; while extensive, it is largely a syntax migration rather than adding new project functionality.
