Side B removes real dead code and a duplicated code path (ExpandNewThreadForm action plus its toolbar), unifying home page compose rendering with room pages via direct SSR—reducing complexity and maintenance burden. Side A adds a legitimate feature (vote counts, unpin form) but with more surface area of speculative UI polish (CSS across two themes, vote count formatting) that is less structurally significant than B's consolidation, though A does include a solid regression test for its new helper function.
