 For the cases where you don't want Svelte's reactivity to apply deeply to state, and for those who might want to have more control over their data structures, you might find `$state.raw` useful. Furthermore, `$state.raw` is ideal for those who want to work with data using immutable patterns rather than mutable patterns.
