⛔ Two clauses one sentence apart cancelled each other out. The card said a
redaction destroys the samples under a picture, "which is what a reader of
scanned paper needs, a scan being one picture across the whole page", and then
that it refuses "a JPEG above all". Every scanner writes DCTDecode. The
scanned page the landing offered was the one page a scanner cannot make.

ops v0.38.0 decodes
the JPEG and writes it back as plain samples rather than re-encoding it:
re-encoding re-quantises the photograph block by block and would degrade every
block in order to destroy a corner of it. What goes back is exactly what a
reader of the original would have seen, with the region gone — the file grows
instead of the picture changing.

The refusals that remain are named instead of being covered by a sweeping
one: a picture drawn turned or twice, one carrying a mask, a CMYK JPEG (no
faithful way back to RGB without the profile the file does not carry), and
anything past a hundred megapixels — read from the header, because a JPEG
declares its size in a handful of bytes and a decoder then asks for
width × height × 3.

landingmigrate repeats layouts/index.html after the edit: 0 hideable, the
four fragments it lists all KEPT, says more as before.
