# Headless gameplay test: run with
#   godot --headless -s res://tests/test_icon_button.gd
# Verifies IconButton correctly turns a touch-down + touch-up into its
# `pressed` signal, which the Map button is wired to open the world map -
# and that opening the map hides the Map button itself (avoiding it
# overlapping the Close button, which occupies the same corner).
#
# Calls _gui_input directly rather than routing a synthetic touch through
# the viewport's screen-position hit-testing, since headless mode's
# placeholder window makes exact on-screen coordinates unreliable to
# target (see test_world_map_ui.gd's pan test for the same issue) - this
# is a more targeted unit test of the button's own press logic anyway.
