# Drive a JAPANESE title capture end to end, and ALWAYS put the locale back.
#
# The first JP capture (2026-08-30) demonstrated the logo stack is at rest
# WITHIN a run: five frames ~1.5 s apart, byte-identical over the port's ROI,
# against a whole-frame contrast control showing 5-8 % of the screen moving.
# That does not test the axis sylpheed-port's drift was on -- BETWEEN runs, where
# a free-running clock lands somewhere else on a fresh boot. This script exists
# to take a second, independent capture so that axis can be measured.
#
# Usage: jp_title_session.sh OUTDIR [wait_s]
