"""
HTTP Server Entry Point for Nadlan-MCP.

Serves three things on a single port:
  /              → React SPA (search & browse Israeli real estate data)
  /api/...       → REST endpoints used by the SPA (also documented at /api/docs)
  /mcp           → FastMCP streamable-http endpoint (for LLM clients)

For local Claude Desktop integration, use run_fastmcp_server.py (stdio).
