The unrooted *.pdf and *.png rules hid anything added under figures/.
Build products are all at the document root, so the rooted rules are
enough.

veraPDF was wired in as a make dependency, which it should not be: it is a
check to run by hand, not something a build needs installed. The validate
target goes away.
The vc target came back. It generates the git revision file and was lost in
the port, so \input{vc} had nothing to read. spell came back with it.
notes.config is deliberately not restored. It existed to flip
\setbeameroption between slides, notes-on-second-screen and notes-only, and
ltx-talk has no such option: the slides build never contains notes and the
notes PDF is assembled afterwards by mknotes.
fonts.tex has to be kept out of the wildcard. It is a fragment with no
\documentclass, and make otherwise tries to typeset it and hangs waiting
for input.

Beamer cannot produce a genuinely tagged PDF. The master template
validates as PDF/UA-2 only because tagpdf marks everything it was not
told about as decorative, so a screen reader gets the frame titles and
nothing else. Beamer 3.77 then made matters worse by refusing
\DocumentMetadata outright, which breaks tagging on TeX Live 2025 and
leaves the deck failing validation altogether.
ltx-talk was written by the LaTeX Project with tagging as a design goal.
The slides built here carry real paragraphs, lists as L/LI/Lbl/LBody,
sections as headings, formulas as MathML, and alt text that reaches the
PDF. veraPDF passes on the strength of that structure rather than in
spite of its absence.
The metropolis theme files go with beamer; trantor replaces them. Fonts,
figures and the purple palette are unchanged.

- Created .gitignore file within the template directory. I believe
that /this/ repository should not know about them but the
new_beamer_presentation should export these so that we don't have to
create a new .gitignore file from scratch every time we create a
presentation.
