vize_atelier_sfc 0.64.0

//! Snapshot tests for TypeScript output mode
//!
//! This module tests the TypeScript output generation for Vue SFCs.
//! It uses the insta crate for snapshot testing, with snapshots stored
//! in tests/snapshots/sfc/ts/.
//!
//! The test cases are loaded from TOML fixtures in tests/fixtures/sfc/.
