0x8050 dies disc-wide (38 sprites, high byte tracks the archive) and again on
EXTRAS, where pteff21/22/23 share it with the frames.
The port's 'neither frame has a fully-opaque pixel' is true and is not the
discriminator: pteff10 has max alpha 130, no opaque pixel, and they measure it as
nearly exact. Their direction survives -- the draw path did answer -- so what is
refuted is the reason, not the conclusion.
