/**
 * Flatten `{ pages: [{ items }] }` — default GODX paginated API shape.
 *
 * TItem USED TO BE ITS OWN TYPE PARAMETER, constrained by `TPage extends { items: TItem[] }`, and
 * that made it uninferable in the one way this function is documented to be used. TypeScript infers
 * a type parameter from ARGUMENT POSITIONS, never from another parameter's constraint, so passing
 * the function by reference — `flatten={flattenItemPages}`, the whole API — left TItem at its
 * fallback and collapsed InfiniteQueryState's TFlat to `unknown`. The catalog example was written
 * with `flattenItemPages as any` and `(items: any)` to silence exactly that, which is how the
 * signature survived (gh#889).
 *
 * Taking the page shape INLINE — `{ pages: { items: TItem[] }[] }` — puts TItem in an argument
 * position, so it is inferred from the real page type and `items` arrives as `Activity[]`. TPage
 * itself was never used for anything but that constraint, so naming it bought nothing.
