Commit A is pure formatting churn in garden.rs (import reordering, line breaks, brace style) with no behavior change. Commit B lands a durable theme design (cookie + POST /theme, server-rendered CSS, login cookie re-issue, localStorage migration) plus lasting API/url fixes (item_path_for_api_in_room, forum_thread_web_url, room-aware RPC/CLI hints and tests).
