# Dom.OptionsByTagName

Element options indexed by native tag name.

## Signatures

```ts
export type OptionsByTagName = {
    readonly [Tag in keyof ElementByTagName]: ElementOptions<ElementByTagName[Tag]>;
};
```

## Why

Generic host utilities can retain exact platform event and property types.

## Ownership and lifetime

Type-only; rendered options follow the selected host's Scope.
