/**
 * ae_events_stores__leads.svelte.ts
 *
 * Svelte 5 PersistedState store for the Exhibitor Leads module local config.
 * Replaces the `events_loc.leads` sub-object from the Svelte 4 persisted store.
 *
 * localStorage key: 'ae_leads_loc'
 * Version gate:     AE_LEADS_LOC_VERSION in store_versions.ts
 *
 * Session state (non-persisted) stays in `events_sess.leads` — same pattern as
 * pres_mgmt and badges.
 *
 * Usage:
 *   import { leads_loc } from '$lib/stores/ae_events_stores__leads.svelte';
 *   leads_loc.current.auth_exhibit_kv   // read
 *   leads_loc.current.tab[exhibit_id] = 'list'  // write
