# nginx config for ReVoltVPN — Reality era
# Path: /etc/nginx/sites-available/hivemind
#
# After Reality migration:
#   - /tunnel and /tunnel-throttled locations are REMOVED
#   - Xray Reality handles the VPN tunnel directly on port 8443
#   - nginx only serves the API (proxied to Flask) and any static website

# ── Rate limiting (uncomment when you need it) ───────────────────────────
# Defines a 10MB shared memory zone tracking request rate per IP.
# 10 r/s with burst of 20 — anything above gets HTTP 503.
