Side A implements a substantive new capability: pool-scoped voting, including `pool` query handling, pair selection from child items, navigation that preserves pool context after voting, UI links to start child voting, and the necessary request/response plumbing. Side B is a small maintenance change that updates the GitHub Actions Node version and removes obsolete tests, which is useful but far less impactful to the project's functionality and design.
