//! Write the wrapper-facing TypeScript types + raw JSON Schemas to disk.
//!
//! The generation logic lives in [`cli::ts_codegen`] (so the drift test can
//! reuse it); this binary just writes the result. Run from the repo root:
//!
//!     cargo run -p heddle-cli --example gen_ts_types -- clients/npm/generated
//!
//! Output is deterministic, so regenerating on an unchanged contract is a
//! no-op diff. `crates/cli/tests/ts_types_in_sync.rs` asserts the checked-in
//! files match.
