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

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

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.
