The query read the typing-debounced search, so for 300 ms after a jump it mixed the new view's
filters with the old view's text and fetched rows neither view shows. useDebounced takes a settle key
whose change applies the value immediately.
Typing in the search box changed the feed/count/facets query keys on every keystroke, so
each query dropped to its loading state and blanked the content — the whole feed area
flickered. Debounce the search term feeding the queries (the input still updates instantly)
so they only re-run after a pause, and keep previous results on screen during a refetch via
placeholderData: keepPreviousData, so the feed and tag counts update in place without blanking.
