A field re-renders only when its own value, error, or dynamic prop changes. Zero ceremony, zero memo gymnastics.

State you don't manage
immer-backed store · survives unmountValues, errors, touched, dirty, focused, disabled, hidden — all in one store.
No useState rows. No reducers. No context.
Restore the form when the component remounts.
Dynamic everything
Required, disabled, hidden, options, validators — any prop can be a function of the form. Dependencies are tracked, not declared.
Dynamic props →Arrays and groups
