// Guards the unfolding of `renderContentAsRawText` back onto the two
// per-surface render keys. The single toggle carried user content and
// thinking at once, so only the user key is restored from it and thinking
// returns to its own default. The toggle is removed from the persisted
// config so it does not stay orphaned in localStorage.
