fontspec does not enable the classic TeX input ligatures by default,
so under lualatex our existing -- / --- / `` / '' input was being
typeset as literal hyphens and straight quotes rather than en-dashes,
em-dashes, and curly quotes.
Add \defaultfontfeatures{Ligatures=TeX} right after \usepackage{fontspec}
in each template that loads fontspec (paper, memo, and letter). The
poster template uses beamer's default fonts (Latin Modern under
lualatex), where TeX ligatures already work via the font tables, so
no change there.
