stargaze 0.1.2

//! Live tests that hit the real GitHub API.
//!
//! These are `#[ignore]` by default so `cargo test` stays hermetic. To run
//! them:
//!
//! ```bash
//! export GH_TOKEN=$(gh auth token)
//! cargo test -- --ignored
//! # or a single test:
//! cargo test live_starred_first_page -- --ignored
//! ```
//!
//! Any test that finds `GH_TOKEN` empty short-circuits with a skip
//! message so an opted-in run on a stale environment doesn't hard-fail.
