# Boot -> TITLE -> arm the UI draw/blend capture there -> (A) -> MAIN MENU -> arm again.
#
# Completes the blend table started in docs/re/structures/ui-blend-mode-measured.md,
# whose stated reach was "two screens, one session" and explicitly NOT the title.
# The second arm at the menu is deliberate: it replicates the main-menu result in a
# SECOND session, which is the part of that page's reach a rerun can actually widen.
#
# Differences from menu_blend_capture.sh, each one paid for:
#
#  * DEADLINE defaults to 1200 s, not 420. On 2026-08-31 a 420 s wait reported
#    "NEVER REACHED THE TITLE" and the emulator, left running, was at the settled
#    title minutes later and took (A) first try. A timeout measures the timeout.
#  * The title arm is gated on the PLATE PULSE (wait_plate_pulse.py), not on
#    screen_id alone: build 2's `PRESS (A)` plate is part of what is being
#    measured, and it pulses.
#  * On timeout it LEAVES THE EMULATOR UP and says so, so the run can be rescued
#    by attaching instead of rebooting.
#  * No --log_ui_draws. Canary's own source records that arming is unconditional
#    now and that launching with the flag correlates with the title refusing (A),
#    0 of 7 runs against 4 of 5 without.
#
# F10 opens Xenia's menu bar, and any Xenia UI makes IsUIActive() true, after
# which XamInputGetKeystrokeEx returns SUCCESS with a zeroed keystroke and the
# guest's unbounded pump queues one entry per poll -- the crash in
# docs/re/structures/title-a-press-fault.md. So the surface is clicked
# immediately after every F10, and stdout is size-checked afterwards.
#
# Usage: title_blend_capture.sh [out_dir]
