Side B removes real duplicated logic (a redundant toolbar and matching server action/tests) by wiring home to SSR the same collapsed compose slot as room pages, simplifying the codebase and reducing surface area. Side A adds a display feature with decent test coverage, but it's a smaller, purely additive UI convenience versus B's genuine cleanup and unification of two divergent code paths.
