/**
 * Sans-I/O Esplora REST API protocol.
 *
 * Every method returns an {@link HttpRequest} descriptor (a plain object
 * describing *what* to request) without performing any I/O.  The caller
 * is responsible for executing the request with an HTTP client of their
 * choice and deserializing the response.
 *
 * This mirrors the pattern used by the Rust `esploda` crate where
 * `Esplora` methods return `http::Request<()>` objects.
 *
 * @example
 * ```ts
 * const protocol = new EsploraProtocol({ host: 'https://mempool.space/api' });
 *
 * // Build a request descriptor (no I/O)
 * const req = protocol.getTx('abc123...');
 *
 * // Execute with any HTTP client
 * const res = await fetch(req.url, req);
 * const tx: RawTransactionRest = await res.json();
 * ```
