/**
 * beta-review regression guard.
 *
 * `renderClient` used to CALL the panel component as a plain function:
 *   renderClient: (props) => HushlePanel(props)
 * The panel's hooks then belonged to whatever component invoked
 * renderClient. The room mounts it conditionally, so the hook count
 * changed between renders and React threw #310, taking the whole voice
 * room down to its error boundary as soon as an activity loaded.
 *
 * Returning an ELEMENT gives the panel its own instance and its own
 * hooks — and an element can be asserted on without a DOM.
