Same parsing rules as extractLedeAfterHeading but with a
larger byte budget so the full BLUF paragraph (typically 200-300
characters in the editorial style guide) is captured for use as
og:description / twitter:description. Returns the joined
paragraph clamped via truncateExtendedDescription (which
returns '' when the result wouldn't be longer than the regular
meta description).
Parameters

Brief body (SPDX preamble already stripped)

Extended lede paragraph, or '' when not worth emitting
