Separate commit on purpose so this can be reverted independently if
needed. Search icon in the Navbar (hidden below sm:, same reasoning
as WishlistLink — Account+Cart are the only always-visible icons on
true mobile) opens a debounced (250ms) overlay searching both
collections at once via a new /api/search route.
Plain Payload `where[...][contains]` queries (Postgres ILIKE), not a
real search index (Meilisearch/Algolia) — matches the catalog's
current small size, see [[project-ecommerce-sota-gaps]]'s own "search
becomes necessary past ~20 products" note. Worth upgrading later
without touching the overlay component itself.
