review headline
The short title a reviewer gives one review ('Great value, runs small'). A qualifier of the review property, bound to one review statement. Free per-review prose (a literal): it identifies one review's title, never recurs across products as a filterable category.
Review headline is free text, written for one product alone and never shared as a category.
It is a qualifier of review — it has meaning only inside a review statement, one per statement, never on its own. It belongs with review to social proof — what buyers and critics say about it.
It is answered inside every review statement, not as a standalone question on a kind.
