 * narrow save/restore so a user's clipboard survives the test run — the window
 * between save and restore is microseconds.
 *
 * - `confirm` — key (string) or sequence (array) to press after writeText.
 *   Defaults to 'Control+V'. Use ['Control+a', 'Control+v'] for select-all-then-paste,
 *   or 'Shift+F11' for the goto-link dialog.
 * - `postDelay` — ms to wait between confirm-press and restore, for dialogs
 *   that read clipboard asynchronously (e.g. Shift+F11). Default 0.
