Search that settles on the wrong word

The Loaf store has a pantry search: one box, results update live as you type. Each keystroke fires a request to `/api/search` and the matches drop in underneath. Type a single ingredient at a normal pace — `sourdough`, say — and watch where it ends up. The box reads `sourdough`, but the list under it fills with a broad jumble of items, and the counter cheerfully reports the matches "for sourdough" even though half of them have no sourdough in them. Stop typing, wait a second, and it stays wrong. Type the same word slowly, one letter at a time with a pause between each, and it's perfect. Every search, on its own, returns exactly the right matches — you can confirm that by hitting `/api/search?q=sourdough` directly. The list only goes wrong when the letters come fast.
