The esbuild namespace a fetched module lives in. Exported so a plugin that RESOLVES an entry
itself — qunitx run's, which hands esbuild a path rather than a specifier — can mark a URL as
belonging here; a plain path would otherwise be looked for on this disk.
import { REMOTE_NAMESPACE } from './remote-module-plugin.ts'; REMOTE_NAMESPACE; // 'qunitx-remote'
