It must be used together with `@csstools/css-tokenizer` and `@csstools/css-parser-algorithms`.
```ts
import { parse } from '@csstools/cascade-layer-name-parser';
const layerNames = parse('layer-name, foo.bar');
layerNames.forEach((layerName) => {
console.log(layerName.name()) // "foo.bar"
console.log(layerName.segments()) // ["foo", "bar"]
});
```
