They reached a submenu and could not identify it: intensity correlation cannot
discriminate when the candidates are near-blank, which is what the .tbm hypothesis
predicts. Their capture is 99.999% non-black -- a full-screen background our
renderer omits -- and an additive background swamps intensity but not edges.
Control first: edge correlation against my own title capture over seven GP_TITLE
builds picks build 4 at +0.2792, 1.4x over second and 7.6x over third.
Result: GP_TUTORIAL build 0 at +0.4962, build 1 at +0.3137, best GP_SAVE_LOAD at
+0.0713. Winning r higher than the control's and margin better; both TUTORIAL
builds 4-7x above every SAVE_LOAD build. Independently plausible -- flow.json has
ptbtn03 = TUTORIAL -> TUTORIAL_MENU, not a GP_TITLE build.
The ARCHIVE is identified with a large margin; WHICH BUILD is not -- 1.58x is the
same order as the control's 1.4x and the two are variants of one screen.
