Cuts the multi-line rationale blocks down to what a reader of the file
needs. The reasoning behind the tagging setup belongs in the commit
messages that introduced it, not repeated above every \DocumentMetadata
block.
Also trims the README: drops the consequence clause explaining what
happens when the standard is declared without the tagging, drops the
quoted TeX Live 2024 error message, and notes that sid has a new enough
TeX Live for anyone not on Overleaf. Adds the caveat that a veraPDF
PASS is necessary but not sufficient, since a document whose body text
is all artifact passes too.
