Subject: [PATCH] paper + assignment: add PDF metadata via
 pdfmanagement-testphase
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

memoir is not yet compatible with the LaTeX tagged-PDF code, so full
\DocumentMetadata (which pulls in all the latex-lab tagging machinery)
crashes at compile time. Use \RequirePackage{pdfmanagement-testphase}
plus \DeclareDocumentMetadata to get the PDF-management layer — document
language, PDF 2.0 — without triggering tagging. Also adds pdflang and
pdfdisplaydoctitle to the existing hypersetup.

The \DocumentMetadata block and tagpdf load are left in the file as
commented-out lines so this is a one-edit swap once memoir gains
tagging support upstream:
