#   => control 1, hold 1  ->  NO AUTO-REPEAT
#   [351.2s] B pressed on the menu
#   [358.5s] TITLE SETTLED (plate pulse detected, glyph 968) -- pressing B
#            B delivered
#   [380.2s] 20 s after B on the SETTLED title: 4.3 % of pixels differ from
#            the moment of the press, glyph 730
#
# 1. NO AUTO-REPEAT. A held direction moves the cursor ONCE. The move spike is
#    0.0202-0.0220 against a noise floor of 0.0003-0.0038, a 5x separation, and
#    the CONTROL (a single tap) returns exactly 1 -- so the counter was shown to
#    count before it was asked to count nothing.
#    Reach: one hold, 2.0 s, DOWN, on the main menu.
#
# 2. B ON THE SETTLED TITLE DOES NOTHING. Twenty seconds after a
#    delivery-confirmed B, the screen is still the title WITH PRESS (A) BUTTON
#    up -- read off the capture, which names itself. The 4.3 % that differs is
#    the plate's own pulse and the light sweeps; glyph 730 sits in the
#    plate-pulse band 714..1520 (plate-pulse-measured.md).
#    This is the run the previous attempt could not be: the press waited for
#    the plate pulse -- the title's own settled signature -- instead of landing
#    during the build-in.
#
# 3. THE PLATE IS RE-DRAWN after B from the menu. B on the menu at 351.2 s;
#    the plate pulse was detected at 358.5 s, ~7 s later. That was the other
#    unevidenced half of the 'B on the main menu' row.
