  // EXCLUDES `benchmarks/` (they are never shipped).  Without this,
  // nothing in CI notices when a `src/` API change orphans a benchmark:
  // the whole suite sat broken on a removed `ask` export (#506) because
  // a missing barrel export is a compile error nobody compiled for.
  //
  // Deliberately narrower than `tsconfig.dev.json` (which also pulls in
  // `tests/` + `examples/`): a tight `src` + `benchmarks` scope is fast,
  // and it is the one the `benchmarks` workflow runs next to
  // `bench:smoke`.  The dev config is green and gated too since #540, so
  // this is no longer the only one that can gate — the two overlap on
  // `benchmarks/` and that is fine: this one fails in seconds, in the
  // workflow that also runs the suite.
