//! End-to-end compile smoke test for Metaplex context constraints.
//!
//! Verifies that `#[hopper::context]` accepts Anchor-style
//! `metadata::*` and `master_edition::*` account keywords, threads
//! instruction arguments into the generated validators/helpers, and
//! type-checks the generated Metaplex CPI builder lowering.
