# 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".
#
# There is no silent-failure path left to press: storing with an empty hold,
# ordering something the crafter cannot pay for yet, and storing successfully
# all report. The queue in particular 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. storing with an empty hold explains where ore comes from
#   2. ordering against an empty stock says it is queued AND how much more
#      ore the building needs
#   3. a successful store reports the amount
#   4. 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
#   5. the message is the FIRST line, not buried under the standing state
