 * } from "@polkadot-apps/host-sdk/identity-adapter";
 * import { IdentityHandle } from "@polkadot-apps/host-wasm";

 * // encoder is the WASM IdentityHandle — it implements IdentityEncoder.
 * const encoder = new IdentityHandle();
 * const resolve = createIdentityResolveUsername(POLKADOT_PEOPLE_TRANSPORT, encoder);
 *
 * // Pass to mountProductView:
 * mountProductView({
 *   // ...
 *   bridgeAdapter: {
 *     identity: { resolveUsername: resolve },
 *     // ...
 *   },
 * });
 * ```

/**
 * Create a `resolveUsername` function backed by the given transport and encoder.
 *
 * The returned function validates the username, builds the storage key via
 * the encoder, queries the People chain RPC, and decodes the result.
 *
 * @param transport - RPC transport (use `POLKADOT_PEOPLE_TRANSPORT` or
 *   `PASEO_PEOPLE_TRANSPORT` from `@polkadot-apps/host-sdk/identity`).
 * @param encoder - WASM `IdentityHandle` instance (or any `IdentityEncoder`).
 * @returns An async function matching the `HostBridgeAdapter.resolveUsername` signature.
