"""The edge payloads carry the plane's constant as FIXED-POINT screen coordinates,
not floats (0x0000ec00 = 60416 = 236.0*256, a screen-x). Dump the edge SEND payloads
reading each word as float AND as fixed-point (/256, /65536), and flag values that fall
in the object's screen range x[126,255] y[0,93] — those are the C / vertex terms."""
