Covers the build targets, why only the slides build is expected to
validate, and how the notes are captured. Also records the known gaps so
they are not rediscovered later: frame titles are not emitted as
headings despite the role map declaring frametitle -> H4, overlay
tagging has an open upstream bug for the \only forms, and talk-notes.sty
depends on two ltx-talk internals that a future release may rename.
