# Headless gameplay test: run with
#   godot --headless -s res://tests/test_crafter_feedback.gd
# Every press in the ship crafter must say what happened. Reported twice from
# play-testing as "the buttons do nothing".
#
# The queue is invisible by nature - an order that cannot be afforded is
# accepted and waits (#16), which looks exactly like a dead button unless it
# says so.
#
# Verifies:
#   1. ordering against an empty stock says it is queued AND how much more
#      ore the building needs
#   2. the message survives the per-frame status refresh - it used to be
#      overwritten on the very next frame, which is what made a working
#      button look dead
#   3. the message is the FIRST line, not buried under the standing state
#   4. the panel is opened the way the GAME opens it - park the fleet on the
#      crafter and press the action button - and its buttons then work
#
# Point 4 exists because this test used to set craft_building_id by hand.
# That skipped the one step that was actually broken: opening the panel
# stopped recording WHICH crafter, so every handler bailed out at its `== 0`
# guard while the panel still opened. Reported four times as "the buttons do
# nothing", and invisible to every test that set the id itself.
#
# Storing ore used to be tested here too. It moved out of this panel entirely
# in #24 - see test_resource_transfer.gd.
