# ForwardedHostKeys

Option keys forwarded directly to a component host.

## Signatures

```ts
export type ForwardedHostKeys<Options> = Extract<keyof ObjectValue<Options>, EventHandlerProperty | "ref">;
```

## Why

Top-level refs and events remain ergonomic while other DOM props stay under `props`.

## Ownership and lifetime

Type-only; the rendered host owns listener/ref lifetime.
