//! Comprehensive Gamma API endpoint explorer.
//!
//! This example dynamically tests all Gamma API endpoints by:
//! 1. Fetching lists first (events, markets, tags, etc.)
//! 2. Extracting real IDs/slugs from responses
//! 3. Using those IDs for subsequent lookups
//!
//! Run with tracing enabled:
//! ```sh
//! RUST_LOG=info,hyper_util=off,hyper=off,reqwest=off,h2=off,rustls=off cargo run --example gamma --features gamma,tracing
//! ```
//!
//! Optionally log to a file:
//! ```sh
//! LOG_FILE=gamma.log RUST_LOG=info,hyper_util=off,hyper=off,reqwest=off,h2=off,rustls=off cargo run --example gamma --features gamma,tracing
//! ```
