# Read-only Package Preview Prototype

This is the first authoring-system vertical slice. It reads a Scrivener project, checks the project structure, and builds an on-screen package preview. It does **not** call a model and it does **not** write to Scrivener.

Run from `Authoring_System`:

```sh
python3 prototype/app.py
```

Then open [http://127.0.0.1:8765](http://127.0.0.1:8765).

To point it at another project:

```sh
python3 prototype/app.py --project /absolute/path/to/Book.scriv
```

The app binds scene/brief pairs by the visible `Scene X` labels for this read-only prototype. The next phase will persist UUID bindings in a sidecar, so later renaming does not break relationships.
