- DXNOrderedMap
- DXN `ordered-map` (`@ordered %{...}`) -- order is part of value identity. Wrapped rather than a bare associative PHP array (which already claims `map`, the no-ordering-guarantee sibling) so the two stay distinguishable on encode; also because a DXN map/ordered-map key can be any DXN value, not just an `int|string` the way a native PHP array key must be.
