Maximum og:description / twitter:description length we will
emit. Facebook truncates at ~300 characters in the preview card;
Twitter at ~200. We aim for the longer cap so LinkedIn / Slack
(which use the full OG payload) get the full BLUF context, then
let Twitter clip naturally. Below this length the extended
description is emitted verbatim; above it we sentence-boundary
truncate.
