//! Read the native TRON order-book market.
//!
//! No signer is required. `"_"` is TRON's reserved token ID for native TRX.
//!
//! Optional env:
//!   TRON_SELL_TOKEN_ID — sell-side TRC10 ID (default: 1002000)
//!   TRON_BUY_TOKEN_ID  — buy-side token ID (default: _ for TRX)
//!   TRON_ORDER_ID      — 32-byte order ID in hex
//!   TRON_ADDRESS       — account whose orders should be listed
//!   TRON_API_KEY       — TronGrid API key
//!
//! ```bash
//! cargo run -p examples-exchange --example market_queries
