      # drift from rc6 — if the wallet_ffi ABI mismatches the module build, fall
      # back to cherry-picking #629's one line onto e37876a and pin that commit.

  # NOTE: this flake is no longer built standalone. The amm_client_ffi crate
  # (the Rust C FFI library the AmmUiBackend C++ code links against) lives in
  # the repo-root flake, and referencing it from here would require either a
  # hardcoded absolute `git+file://` path or a `path:../..` input — the latter
  # fails flake evaluation because the app directory is copied into the Nix
  # store as its own flake root, so `../..` can't escape it there. Instead,
  # the repo-root flake.nix builds this module directly (src = ./apps/amm)
  # and resolves amm_client_ffi via `self`. The repo-root flake exposes the UI
  # as a named attribute (there is no bare `default`): run it from the repo root
  # with `nix run .#amm-ui`, and build just the FFI crate with
  # `nix build .#amm_client_ffi`.
