  # Note: To avoid compile-time warnings in environments where `:file_system` is not present
  # (e.g., `:prod`), we use `apply/3` instead of direct function calls.

  # This ensures the compiler does not resolve `FileSystem.start_link/1` or
  # `FileSystem.subscribe/1` unless the module is actually loaded at runtime.
