"""Is this frame the interactive title screen? Exit 0 if yes.

Counts the pixels of the **green (A) glyph** in "PRESS (A) BUTTON" anywhere in
the frame. That is the one thing only the interactive title has, and counting is
geometry-independent — unlike the single absolute pixel this replaced, which was
a 1280x720 coordinate being sampled against the 1279x675 game surface and always
read the copyright line.

`screen_id.py` is too loose for this job on its own: it called the SQUARE ENIX
publisher logo "title" 151 s into a boot, and skip_intro spent its one press
there. Measured on a real title frame: 1442 glyph pixels, centred near (622,572).
