//! Compile-time API surface verification for all 13 formats.
//!
//! Tests that every format module exposes the expected set of functions.
//! If any format regresses (e.g. someone accidentally deletes `parse_content`
//! or `to_string`), this file will **fail to compile** — a stronger
//! guarantee than runtime checks.
//!
//! Async generic functions (generate, write_stream) are NOT checked here
//! because their type parameters can't be inferred from bare references.
//! They're verified by the existing runtime test suite (api_surface tests,
//! integration.rs, pipeline_integration.rs).
