+// tui_script: scripted headless session over the demo scene, to diff against python.
+// Script lines (stdin):
+//   feed <hex>        stdin bytes -> TuiInput -> app.dispatch
+//   flush             TuiInput.flush() -> dispatch (lone ESC resolution)
+//   frame             print hex of app.frame_bytes()
+//   text              print app.render_text()
+//   resize R C        like SIGWINCH: new size, invalidate, dirty_layout, Resize event
+//   shell <text>      feed text (with \r\n for \n) into the demo shell screen
+//   ask               open the demo question dialog (F1 path)
+//   sources           install the completion sources used by the prompt dialog
