Re-record the animated demo MP4 at docs/demo.mp4 using the `--demo-for-recording` dev mode, then refresh the GitHub user-attachments URL embedded in the README. Invoke when the HUD, biscuit art, sidebar, panels, or any visible feature has changed enough that the existing demo no longer represents the current version of the game.

Use tu to visually drive and test forestui in headless terminals. Invoke PROACTIVELY when fixing behavioral/visual bugs or developing new features — don't wait to be asked. Lint and typecheck can't catch UI regressions, wrong window names, or broken interactions.
