The lecture's pitfall list: "ikke glemme brukervalg ved reload av side". - [ ] `q`, `genres`, `decades`, `sort` in the query string via `useSearchState` - [ ] back/forward works - [ ] a result view can be shared as a link - [ ] any change to query/filter/sort drops the cursor (back to page one) **Acceptance:** reloading or pasting a URL reproduces the same result set and controls.
