Ring at 347.5 on entry, 427.5 after one confirmed DOWN, 347.5 on re-entry with the
frame 0.0 % different from the first entry. sylpheed-port asserted non-persistence
when nothing had measured it; the assertion was right and is now measured.
MISSION SELECT is therefore a genuine initial focus, because this screen resets --
unlike the main menu, where a single-entry reading measures history.
Every control here exists because run 1 failed without it: absolute row checks
after every navigation press (a constant offset passes a differential control),
screen identity against an in-run reference frame (main menu 327, EXTRAS 324 and
OPTIONS 317 all sit in the same glyph window), and raw ring rows inside the
submenu so no three-item geometry is assumed. The screen was also confirmed by eye.
