Answers the port's ask about ptframe1/ptframe2, whose residual is uniquely higher on
flat pixels than edges and signed one direction -- a body-intensity difference.
Prior work covers .prm primitives and a refuted T8aD +0x04 bit; neither covers a
.t32 element. All 15 words of the 60-byte declaration entry are read: 3 are the
name, 8 constant, the rest kind, focus index, position and pivot. The frames are
kind 0, identical to every other plain sprite.
One candidate found and refuted by myself: T8aD +0x08 is the only word where both
frames agree uniquely on that screen, at 0x8050 -- but 38 sprites carry it
disc-wide, only 8 named frame, and the high byte tracks the archive. It is an
atlas/format word, not a mode.
Also records a false positive of my own test: +0x00 and +0x08 first read as
'separating the frames' because those words are the name string.
So any blend the port picks is authored. Reach: not looked at the executable's draw
path, where a mode selected in code rather than data would live.
