## Identity

Generated `packages/frontend/src/App.tsx` and `@sapporta/frontend` app/shell exports.

## Contract

- `appNavigation` is a `Navigation` value rendered by the generated shell.
- `appHomeRoute` chooses the signed-in landing destination.
- `appPublicRoutes` render outside the protected app gate.
- `appProtectedRoutes` render after auth bootstrap inside `AppShell`.
- `getApiBase` and router helpers provide platform integration for project screens.
