// React binding of the events store (wix/events/events-store.ts) — the listing state machine
// lives there, framework-free; this hook subscribes to one instance per mounted listing and
// exposes its state and actions under one name. SSR-friendly: pass server-fetched data as
// `initialEvents` (+ `initialTotal` from fetchEventsPage, so "load more" knows there is more) and
// no client fetch happens; a SPA passes nothing. Astro islands and React SPAs use this; a static
// page, Vue, or Svelte uses the store directly.
