"""Categories collected but not shown.

Rian, 11 Sep: skincare and confectionery are outside the launch scope. They keep being
collected (the data is cheap and may matter later) but must not appear anywhere Adam
would read as a promise: the mega menu, the shelves, search, counts, brand pages, the
sitemap. Perfume and makeup stay. This pins the set and its shape; the SQL rule
(`catalog_queries.shown_category`) is exercised by the route tests against SQLite.
