/**
 * Combobox Svelte — `createComboboxStore` store-contract bindings (ADR 0034).
 *
 * Import from `trellis/combobox/svelte`:
 *
 *   const combobox = createComboboxStore({ items, onSelect });
 *   {#if $combobox.state.open}…{/if}
 *   <input bind:value={$combobox.query} />
 *
 * No dependency on the svelte package — only the store contract
 * (`subscribe(run) => unsubscribe`, `run` invoked immediately), so it works
 * across Svelte 4/5 (see `src/svelte/stores.ts`, `trellis/forms/svelte`).
 *
 * @module trellis/combobox/svelte
