  // narrows `exclude` (an override replaces the parent list, so the parent's
  // entries are repeated). Selected by typescript.tsconfigPath in
  // next.config.ts. Next's CLI checker (default since 16.3) checks the
  // complete project it is given, so tests must be excluded here rather than
  // relying on the old API checker, which silently dropped their diagnostics.
