The human reports the real game shows multiple, possibly more than two, running
along blue PCB-like traces, and cannot tell whether it is one light per line or
one glow spanning several.
Census of declared travel over every title element: only pteff03 (2160 px) and
pteff03a (2560 px) move as lights. The logo pair travels 300 px but is the logo
sliding in. Everything else -- pteff00/01/02/04, ptlogo_back2eff and eff1..5,
ptlogoall_eff/eff2, ptcopyright, ptbase2 -- declares no travel at all.
So the port renders two full-height streaks crossing the screen where the human
describes a population of smaller lights. Both agents had been asking WHEN the
sweep starts; the port may have the wrong effect altogether, and 'starts too
early' is what a wrong effect looks like to someone not reading keyframes.
Limit flagged on the Decoder's scan: it covered quads taller than 1.2 NDC, so it
cannot count small per-trace lights. pteff03a's absence stands (3.62 NDC); 'only
one travelling quad exists' does not generalise below the filter.
Limit flagged on this census: it reads DECLARED positional keyframes, so it
cannot see UV-scroll or shader-driven motion -- now a live possibility.
