trantor is Marco Pompili's Metropolis-like theme for ltx-talk, added
under its MIT license so the deck keeps roughly its present look after
the class change. Two things differ from upstream: font selection moves
out to the document, since this template ships OpenSans and RobotoMono,
and the Euler maths font it loaded by default is dropped because
lum-euler is not packaged in Debian's TeX Live.
