rem  Editors such as Cursor and VS Code claim the .py extension via the per-user
rem  UserChoice registry key, so double-clicking a .py file opens the editor
rem  instead of running it. .cmd is always executed by the shell, so this gets
rem  the converter running without changing any file associations.
rem
rem  Drag a CSV onto this file to preselect it, or just double-click and pick
rem  both files from the dialogs.
