  #
  # A "press the buttons in the right order" puzzle. Players press a set of buttons;
  # if they enter the correct sequence, a trigger fires (open a door, spawn loot,
  # etc.). Any wrong press resets their progress. Each button knows its own id via a
  # small per-button handler object.
  #
  # Teaches: per-button handler objects carrying state, tracking ordered progress in
  # a single index, comparing against a configurable solution, resetting on error,
  # and firing a trigger on success.
  #
  # Setup:
  #   * Buttons holds the button_device(s).
  #   * Solution lists the button INDICES (into Buttons) in the required press order,
  #     e.g. array{2, 0, 1} means "press button 2, then 0, then 1".
