Ctrl+S always built .odt bytes and wrote them into whatever handle was open — including a handle obtained by opening a .docx, silently overwriting it with ODF content under its old name. Track the loaded format and route Save through the matching exporter and handle; the title's extension label now reflects it instead of a hardcoded .odt. Save As stays .odt-only, so it switches the format back.
