//! E2E tests for `forge-success-status-code` change.
//!
//! Verifies that:
//! - (a) `#[forge(method = "post", status = 201)]` on a bare-type fn produces
//!   HTTP 201.
//! - (b) `ServiceResponse::success_with_status(data, 201)` produces HTTP 201
//!   even without the macro `status` arg (dynamic path).
//! - (c) A bare-type fn without `status` produces HTTP 200 (zero-breaking
//!   regression).
//!
//! Run with: `cargo test --test status_code_tests --features http`.
