    method: "POST",
    headers: {
      "Content-Type": file.type || "application/octet-stream",
    },
    body: file,
  });

  if (!response.ok) {
    throw new Error("Package processing failed");
  }

  return response.json();
}

AI Coding Instructions

• Keep System.IO.Packaging usage inside Pams.Core or another .NET service layer; TypeScript clients should interact through an API boundary.
• Treat package streams as disposable resources and close package objects after reading or writing content.
• Preserve package part URIs and relationship identifiers when updating an existing legacy-format package.
• Check package input for missing parts, invalid relationships, and unsupported content before processing it.
