- CLI binary: `ssr-boost`.

## Data loading contract

Loader and action promises stream by default in Data mode. Return `{ fast, slow: fetchSlow() }` and consume `slow` inside Suspense with `<Await>` or React 19 `use()`. The browser reconstructs native promises before creating the router; client navigation loaders keep their native promises. See [Stream loader data](https://lomray-software.github.io/vite-ssr-boost/guide/data-streaming) for the supported value matrix, errors and opt-in `hydration: 'early'`. Custom `getState` snapshots still use JSON.
