      # numbl is a `file:../../numbl` dependency: we use its compiler internals
      # (parser, lowerer, IR, inline pass) and its interpreter, which its
      # published package `exports` do not expose. Clone it where that relative
      # path expects it. Pinned so a change to those internals cannot silently
      # break the build — the surface we rely on is written down in
      # src/mgpu/numbl.d.ts.
      #
      # numbl's own dependencies are NOT needed: the slice we import is
      # self-contained TypeScript, verified by building against a checkout with no
      # node_modules. One file in it is generated rather than committed, though —
      # the interpreter's stdlib bundle, which numbl gitignores — so a bare
      # checkout is missing it and `executeCode.ts` fails to resolve it. Its
      # generator only reads .m files off disk, so plain `node` (type-stripping,
      # unflagged since 22.18) runs it without installing anything.
