+
+/// Eingabefeld ohne macOS-Text-Ersetzungen (Anführungszeichen, Gedankenstriche,
+/// Auto-Korrektur, Punkt-Verdopplung, Vervollständigung, Links/Daten-Erkennung).
+/// Hintergrund: Normale Textfelder ersetzen still z. B. `"` durch „“ und `--`
+/// durch — (je nach Tastatur-Einstellung). Im Terminal fällt das nicht auf, aber
+/// ein Passwort mit Sonderzeichen kommt falsch bei ssh an → „Permission denied",
+/// obwohl das Passwort „stimmt" (docs/ERRORS.md #13).
+/// NSTextField kann das nicht alles abschalten, daher NSTextView-Basis.
+/// Secure-Modus nutzt NSSecureTextField (per Design ohne Ersetzungen).
