// Pattern A FinalMaskForm. Renders a Fragment of Form.Items at absolute
// paths under `name`; the parent modal owns the Form instance.
//
// Naming convention inside Form.List: AntD prefixes Form.Item `name`
// with the Form.List's own `name`. So Form.Items inside the render
// prop use RELATIVE paths (e.g. `[field.name, 'type']`). Nested
// Form.Lists also use relative names. Using absolute paths here would
// double up the prefix and silently route reads/writes to the wrong
// storage path.
