# ONE blocking session: boot -> Stage 02 in flight -> sweep the view and press
# F10 several times, so each press dumps xenia_ship_capture_NN.log with whatever
# capital ships are on screen at that moment.
#
# Why a sweep and not a single press: the 2026-07-26 e106 capture missed the
# bridge because it was culled at that camera angle. Several presses at
# different headings cost nothing (the capture is a one-frame draw dump) and
# each one is independently correlatable.
#
# Usage: ship_capture_session.sh [presses] [out_dir]
