  # A classic "lights out" style puzzle. Players press buttons; each button toggles
  # a specific set of lights. When every light matches the target pattern, the
  # puzzle is solved and a trigger fires. Lights are discovered at runtime via a
  # gameplay tag, so you don't have to wire each one by hand.
  #
  # Teaches: gameplay tags + GetCreativeObjectsWithTag, per-button event handler
  # objects, casting a creative object to a device type, storing & cancelling event
  # subscriptions, and a <decides> "is solved?" check used in a failure context.
  #
  # Setup:
  #   * Tag every customizable_light_device in the puzzle with the puzzle_light tag.
  #   * Fill Buttons with the button_device(s) players press.
  #   * ButtonToLights[i] lists which light indices Buttons[i] toggles.
  #   * TargetPattern / StartPattern length must match the number of tagged lights.
