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:

Moves paper, assignment, and letter templates from pdflatex to
lualatex, and replaces the Type-1 font setup (mathdesign/garamond,
ucs/utf8x, T1 fontenc) with fontspec using EB Garamond for the main
font and TeX Gyre Heros for sans. This produces PDFs whose text
extracts cleanly and is a prerequisite for tagged/accessible PDF
output.
