ErrorBoundary

func ErrorBoundary(child any, fallback func(err error) View) *viewNode

ErrorBoundary wraps a component and catches any panic that happens during its Body. The fallback callback produces the replacement view.

gova.ErrorBoundary(UserProfile{UserID: id}, func(err error) gova.View {
    return gova.VStack(
        gova.Text("Could not load profile").Bold().Color(gova.Destructive),
        gova.Text(err.Error()).Color(gova.Secondary),
    ).Padding(gova.SpaceLG)
})

child may be a View, a Viewable, or a *componentNode. Non-component views are passed through without wrapping; the guard only applies to component renders. Panics that are not error values are wrapped with fmt.Errorf("%v", r) before they reach the fallback.
