Side B adds a durable end-user feature: a new `CopyGardenRank` UI action, server handler, markdown generation for ranked/unranked garden items, copy buttons in garden views, permission checks, and integration/browser tests verifying clipboard behavior. Side A largely removes a complex autocomplete system and replaces it with a much simpler paste-and-go flow, which simplifies maintenance but also drops substantial functionality in favor of basic URL parsing and redirect behavior.
