📋 General description or bullet points

Provide a way of using clientOnly without creating a separate file.
Code wise, this could be more ergonomic.

Could also create a helper function to directly translate component function to client only component.

import { clientOnly } from "@solidjs/start"

function ClientOnlyComponent() {
  const location = window.document.location
  return <div>{location.href}</div>
}

type ResolveClientComponent = (value: {
  default: Component
}) => void

export default clientOnly(
  () =>
    new Promise((resolve: ResolveClientComponent) => {
      resolve({ default: ClientOnlyComponent })
    }),
)

🖥️ Reproduction of code samples in StackBlitz

StackBlitz doesn't support solid-start

Start with the clientOnly reference at https://docs.solidjs.com/solid-start/reference/client/client-only and inspect the existing clientOnly entry point. Determine how an inline component or helper could be supported without a separate file, then verify that the documented usage works without StackBlitz. Done means the requested ergonomic form is defined and supported by the API.
