# Does the main menu REMEMBER its cursor across menu -> title -> menu?
#
# menu-navigation-semantics.md carries this 🟡: "Initial focus is reproducible
# but not established as invariant. Both of my boots opened on TUTORIAL, and
# both used boot_menu.sh." Two runs through one harness are not two samples --
# the same shape as two captures through one gate (plate-pulse-phase-lock.md).
#
# And the sources DISAGREE. boot_menu.sh's own final line says "cursor on NEW
# GAME"; the page says TUTORIAL 2/2; menu-state-in-memory.md reaches EXTRAS in
# four downs, which only counts from NEW GAME. Two say NEW GAME, one says
# TUTORIAL.
#
# ONE BOOT settles both, and the round trip is the part no run has done:
#   F1  focus when the menu first appears           <- re-measures initial focus
#   F2  focus after 2x DOWN                         <- CONTROL for the reader
#   F3  focus after B (to title) then A (back)      <- persist or reset?
#
# F3 == F2 => the menu restores where you were; F3 == F1 => it resets.
# If F2 is not two items below F1 the reader is not tracking the cursor and
# NOTHING below it may be read. Run as ONE BLOCKING FOREGROUND call.
