Let's wait until #1110 is merged, then change this line to

ui_index = resolve_railtracks_home() / "ui" / "index.html"

As now we rely on absolute path generate by the paths/resolve_railtracks_home function.

if not ui_index.exists():
print_status("UI not found — downloading...")
download_and_extract_ui()

update_thread = threading.Thread(target=check_for_ui_update, daemon=True)
update_thread.start()
