"""The written half of an airport page: where the duty free actually is.

The structure proposal's airport page is about the duty free situation at that
airport and nothing else — where the shops are, terminal by terminal, which
specialty boutiques sit around them, a map where one helps. It is written,
because the data holds a shop as "a retailer at an airport" and knows nothing
about terminals or named boutiques within one (`app/models/hubs.py`). When the
collectors can name a terminal the structured half moves there; the colour
stays here either way.

Why in code rather than a table: it is a few paragraphs per airport, changed a
few times a year, reviewed like the rest of the site's copy. Both renderers read
it — the SPA through `/api/airports/{iata}`, the crawler's body through
`seo.airport_body` — so the two pages cannot drift.

Nothing here is guessed. An airport with no entry simply has no guide, and the
page says so in the demo's placeholder view rather than inventing filler.
