cameo 0.1.1

//! Showcase the CameoClient facade — the primary way to use cameo.
//!
//! Covers all trait methods: search, details, discovery, recommendations,
//! seasons, and watch providers. This example doubles as an end-to-end smoke
//! test for the unified interface.
//!
//! Usage: cargo run --example facade_showcase [query]
//!   (reads TMDB_API_TOKEN from .env or the environment)
