+//! Phase 13 (Track L.11) — TypeScript framework adapter integration tests.
+//!
+//! Mirrors `tests/js_frameworks_corpus.rs` against the TS fixtures.
+//! The Express / Koa / Fastify adapters are registered under
+//! [`Lang::JavaScript`] only and do not currently dispatch for
+//! [`Lang::TypeScript`], so only the Nest adapter — which is
+//! registered under both [`Lang::JavaScript`] and [`Lang::TypeScript`]
+//! because Nest is TypeScript-first — has TS coverage here.
