+   EVENT DATA
+
+   One request, filtered per section. The Retreats page has three
+   bands of events, and all three call this hook — the cache in
+   api.js keys on the path, so they share a single fetch and each
+   narrows the result to what it shows.
+
+     useEvents({ section: "national" })   one band
+     useEvents({ host: "northwest" })     a region's own events
+     useEvents({ status: "upcoming" })    a home page strip
+     useEvents()                          everything
+
+   Filtering here rather than in the query keeps the endpoint to
+   one cached response. At a few dozen events that's the right
+   trade; if the list ever runs to hundreds, move the filters into
+   the URL and let each become its own cache entry.
