/**
 * Upload Svelte — `createUploadStore` store-contract bindings
 * (ADR 0034 wedge 5).

 *   const upload = createUploadStore({ transport: httpTransport });
 *   // In markup: {#each $tasks as task (task.id)} {task.name} {task.progress}
 *
 * No dependency on the svelte package — only the store contract, so it
 * works across Svelte 4/5 (see `src/svelte/stores.ts`).
