Research direction

Start with gui/components/FileChooser.java at create and resources/exporting/impl/ZipExport.java at promptForExport, then reproduce Save as or Decompile and save on Windows with Java 21. Check the DarkLaf file chooser stack trace and verify that export completes without the delegate-related NullPointerException.
