1. [correctness] [apps/swift/static/app.js:32](/home/paulca/amadan.net/carlos/todomvc-bakeoff/.worktrees/swift/apps/swift/static/app.js:32): Every action response removes the entire list, including any active editor. Toggle one item, then start editing another before the response arrives: the replacement discards the draft and focus without saving. Serializing requests does not protect unsent edits. Preserve active editor contents and focus across updates, or defer replacement until editing finishes.
