Five items, written down here rather than only in a message, because a request
that lives in one conversation dies with the container. Two are blocking P3 (how
to recognise the splash bundle, and what the ~0.4 s fade-out actually measures),
one is cheap and prevents P5 rework (focus drawn over vs instead of the base --
the port picked replace without evidence, and the oracle says it picked wrong),
one needs a joint decision rather than a unilateral one (whether the port should
draw the newly-decoded rotation and thereby become deliberately more correct than
the renderer it verifies against), and one calibrates whether RMSE against
captures has a floor at all.
