Why IngramSpark rejects the PDF

Fonts, PDF/X, color. The factory exports; you do not fight Acrobat.

Their file guide wants press-ready PDF: embedded fonts, sometimes PDF/X-1a or X-3, no extra crop marks.

If the reject is the interior, return to Path A or B and download the variant they asked for. If it is the jacket, Path D with the real page count.
