"""The school page's header flags (nextjs-app/lib/schoolFacts.ts) read seven
school_info fields, so the detail payload must carry every one.

It lacked admissions_policy, so no school page could flag Selective while its
search row did: Tiffin and The Grammar School at Leeds showed the tag in
search and nothing on their own pages.
