"""UNWRITTEN - UI kit headless test. Owner: Agent A.

Builds a scene, exercises every widget (DialogueBox with a real node from
script_act1 'intro', a MenuList with a disabled row, a Bar at 30%, a Toast, a
TitleBanner), drives mcrfpy.step to advance the typewriter, and screenshots two
meaningful states.

Run:
  cd build && ./mcrogueface --headless --exec ../games/unwritten/tests/test_ui_kit.py
