 - When a public app file grows large, prefer moving GUI-free app-owned calculations, export builders, formatting utilities, deterministic image/signal transforms, and focused control construction into `apps/<family>/<app_slug>/+<app_slug>/...`.
 - Do not add new `apps/<family>/private/` helpers unless the helper is genuinely shared by multiple apps in that family and the user approves that family-level boundary.
 - Keep the public app entry point responsible for GUI state, callbacks, user alerts, app workflow order, debug launch routing, and user-facing log wording.
