B adds a complete, well-scoped feature (garden ranking clipboard copy) with a new UI action, markdown formatting, unit tests, an integration test, and a browser test plus docs update — genuine lasting functionality. A merely deletes a stale duplicate forum.rs, which is a necessary but narrow fix cleaning up a mess from an earlier split (no new capability, just removing dead/duplicate code).
