//! No-op schema derives for production app-server protocol builds.
//!
//! The real `ts-rs` and `schemars` derives are only needed when regenerating
//! the vendored protocol exports. Normal builds retain the annotations so the
//! protocol definitions stay readable, but use these derives to avoid
//! generating implementations that cannot be reached at runtime.
