Article markup is missing headline or a date

What this means

An Article, BlogPosting or NewsArticle block is present but carries no `headline`, or no date of any kind. Google lists both among the recommended properties for the article rich result: the headline is what the result displays, and a date is how freshness is judged. Without them the block adds type information and nothing else. A block carrying `dateModified` but no `datePublished` is NOT reported — either date answers the freshness question, and demanding both would flag correct markup (web.dev's own articles are published that way).

How to fix it

Add `headline` (the article title as rendered, under 110 characters) and a date — `datePublished` as an ISO 8601 timestamp, with `dateModified` when the piece is updated.

Fix effort

This check needs review: the change can be drafted for you, but a person has to approve the wording or choose the target before it ships.
