Side A is a trivial two-line tweak (removing a heading, fixing a disabled-link element), while Side B is a substantial architectural rework introducing a unified RPC batch API, room-scoped rooms/threads model (replacing ad hoc thread visibility), and corresponding CLI/server/type/test updates across many files. Side B represents real, lasting design work (new API surface, reducer restructuring, updated integration tests) versus Side A's cosmetic churn.
