/// The aggregate form state.
///
/// Constructed once per `<form>` via `App::use_form()`,
/// threaded through the form's inputs and the submit
/// handler. Cheap to `Clone` (the four internal signals are
/// each `Copy`-by-pointer).
///
/// # Field reactivity
///
/// `values`, `errors`, `touched`, and `submitting` are all
/// `Signal`s, so any `html!` body that calls
/// `state.values().get()` (or any of the other three) inside
/// its render closure re-renders when the corresponding
/// signal changes. There is no manual subscribe API; the
/// reactive read IS the subscription.
