Slides-only builds validate as PDF/UA-2, which is what upload targets
check for, but only frame titles and links are actually tagged. Say so
rather than leaving the veraPDF pass to imply more than it means.

The Computer Modern math fonts have no ToUnicode entries, which failed
ISO 14289-2 clause 8.4.5.8 on six checks and left every formula opaque
to assistive software. Switching to an OpenType math font changes the
rendering of math only slightly.

veraPDF reported two metadata failures against ISO 14289-2: nothing
identified the file as PDF/UA (clause 5), and ViewerPreferences was
missing DisplayDocTitle (clause 8.11.2), so viewers announced the
filename instead of the title.

The black page number is illegible against the dark standout background.
Defines a custom frame numbering template that outputs nothing on standout
frames and the normal fraction on all others.

\alert{} is invisible on standout frames due to the inverted color
scheme; fall back to \textit{} using the metropolis@standout boolean.

Switch to LuaLaTeX (better tagged PDF support), add \DocumentMetadata
for PDF 2.0 and language metadata, enable tagpdf tagging, and mark
tikz overlay commands (\credit, \marktopleft, \markbottomright) as
PDF artifacts.
