/**
Check if a value is a plain object.

An object is plain if it's created by either `{}`, `new Object()`, or `Object.create(null)`.

@example
```
import isPlainObject from 'is-plain-obj';
import {runInNewContext} from 'node:vm';

isPlainObject({foo: 'bar'});
//=> true

isPlainObject(new Object());
//=> true

isPlainObject(Object.create(null));
//=> true

// This works across realms
isPlainObject(runInNewContext('({})'));
//=> true

isPlainObject([1, 2, 3]);
//=> false

class Unicorn {}
isPlainObject(new Unicorn());
//=> false

isPlainObject(Math);
//=> false
```
