+//! Trigram indexes so the admin order search stays fast as orders pile up.
+//!
+//! Order search is a plain substring (`ILIKE`) match over the high-signal,
+//! free-text order fields — order number, email, customer/company name — run
+//! through `f_unaccent` so diacritics and case never matter (see
+//! `orders::Entity::search`). These `pg_trgm` GIN indexes let those `ILIKE`
+//! lookups use an index instead of scanning every row. `pg_trgm` + `f_unaccent`
+//! already exist from the product-search migration.
