Side A adds a substantial end-user capability by extending the voting flow with pool-scoped navigation, allowing `/vote?pool=...` to automatically select child pairs, preserving pool context through vote submission, and exposing the feature in the UI with supporting query handling. Side B cleanly adds a useful `RoomList` RPC, CLI command, shared types, and thorough integration tests, but it is a relatively self-contained API addition compared with Side A's deeper integration across routing, UI, navigation, and voting logic.
