A document assigned a CMYK profile (Edit > Assign Profile) keeps it when
it is saved, but the working spaces are the app's, and a new session
starts with the defaults. Opened again, such a document exported its CMYK
colours tagged with the working CMYK space (VectorCraft Generic CMYK
(SWOP-like)) instead of its own profile, made that profile the PDF/X
output intent, and separated its RGB colours through it; print
separations did the same. edit.assignProfile still reported the assigned
profile, and document.exportPdf's documentation says CMYK colours are
tagged with "the document's CMYK profile".
Found on a book cover assigned FOGRA39L Coated: built in several
vectorcraft-cli runs, each reopening the saved document, its PDF/X-4
came out tagged with the SWOP-like profile unless every run set FOGRA39
as the working CMYK space again.
Export and print now work in the document's colour spaces: the active
settings with the assigned profiles in their place (document_cms). An
assigned profile that isn't available leaves the working space, with a
warning.
