[Registration] is a built-in swatch that prints 100% on every plate: Separations
Preview shows it on each process and spot plate and PDF export writes it as
/Separation /All. It can't be edited, moved, duplicated, merged or deleted;
swatch.list shows it after None and the Swatches panel applies it as a swatch.
Object > Create Trim Marks strokes the marks in Registration and marks every
artboard when nothing is selected ({style?, allArtboards?}). The preference
japaneseCropMarks (General) switches to Japanese marks: double lines at the
trim and bleed edges plus centre marks. Effect > Crop Marks (cropMarks) is a
live effect whose marks follow the object; rendering, SVG/PDF export and
Expand Appearance draw them. The mark geometry lives in doc::marks.
