/// The fixture that takes the files away, and a store on a path of its own.
///
/// Both, because the directory lives exactly as long as the binding does: a
/// helper handing back the store alone leaves a file per test behind in the
/// system's temporary directory, where nothing ever collects it.
///
/// The path comes first because bindings drop in reverse order of the pattern.
/// `let (_at, store) = unique_store(..)` drops the store and then the directory
/// it held; the other way round the directory goes while the store still has
/// its file open, the removal fails, and the fixture's `Drop` cannot say so.
