Sheets of several GB are the normal order. The upload limit is now 5 GB.
ClamAV scans files up to 2 GB; a larger file is released only when its
first bytes match the format its name claims, and a disguised file is
refused. The Site grades a sheet over 150 MB from the pixel size in its
PNG, JPEG or WebP header without decoding it, and reads large PDFs in
ranges. The worker never opens a source over 300 MB: a finished sheet
placed whole becomes its own print file, which the Kanban offers to approve
as the final, and anything else goes to hand preparation. Files start
uploading as they enter the cart, with progress in the summary, and each
part renews the reservation so slow uploads do not expire. Quotas grow to
50 GB per customer and 500 GB in total; the Swarm config for ClamAV is
renamed because a deployed config cannot change in place.

Verified locally with a 386 MB and a 1.8 GB PNG (scanned, paid, original
as print file), a 2.3 GB PNG (format check) and a disguised 2.3 GB file
(refused).
