A block that runs long is hard to quote, and quoting is how AI search surfaces a source. Shorter paragraphs also survive the narrow column of a phone screen, which is where most of the traffic reads them. The threshold is not a style rule, it is about extraction. A retrieval system takes a passage whole or cuts it, and when it cuts, the sentence that carried the answer can end up split from the sentence that qualified it. Paragraphs sized to be quotable are the cheapest insurance against being quoted wrongly.

Collapsed when it fires template-wide. If it appears on 90% or more of the pages — or of one language version — of a site with at least 20 pages, it is a property of the template and is reported once, with the count, instead of once per page.
