The previous frame stops a session being written, not read: the browser that
reported this still holds the olive develop under the ORF's name, and a reload
would paint it once more. A session photo named like a RAW is that develop and
nothing else — the RAW branch writes none — so the restore path now reads the
parked RAW first and only falls back to such a copy when there is nothing
parked to develop. An ordinary photo's name is left alone.
Measured in Chromium on the built bundle, with the session poisoned and the ORF
parked: a copy named POISON.ORF opens as the re-developed 1600x1197 frame
(mean 167.3,164.2,138) and a copy named POISON.jpg opens as itself.
