+ * Per-cell `useResolvedPages([id])` calls each mount with a different
+ * queryKey, so React Query can't dedupe them — a 20-row grid with a page
+ * column used to fire 20 requests on first paint. This loader sits under
+ * the hook: incoming id lists accumulate in a pending batch, a microtask
+ * flushes a single `POST /bases/pages/expand` for the union, and each
+ * caller's promise resolves with a Map containing just the ids it asked
+ * for. Unknown ids are absent from the map (hook treats absence as "not
+ * accessible", matching the old per-call semantics).
+ *
+ * Microtask window = one React commit. Cells that mount in a single
+ * commit batch together; cells added later (e.g. infinite-scroll page
+ * load) form their own batch. Good enough in practice; a setTimeout(0)
+ * window would widen it but adds an observable delay.
