# `launch_mission.sh` used to allow a fixed 75 s for the launch cinematic, the
# stage load and the objective card. Under lavapipe that is not a constant: one
# run needed 75 s, the next was still in Raymond's dialogue at 140 s, so the A
# meant for the OBJECTIVE card was swallowed by the cutscene and the card sat
# there forever.
#
# The in-flight HUD is unmistakable: the SHIELD bar is a solid bright green
# block at the bottom of the screen, and no cutscene or menu has anything green
# there. So poll that pixel, and tap A every few seconds until it appears (which
# dismisses the objective card whenever it happens to be up).
