# witryna.conf — Nginx reverse proxy configuration for Witryna
#
# Two server blocks:
# 1. Public site — serves the built static assets
# 2. Webhook endpoint — proxies deploy triggers to Witryna
#
# TLS is not configured here — use certbot or similar to add certificates:
#   sudo certbot --nginx -d my-site.example.com -d witryna.example.com

# Rate limiting: 10 requests per minute per source IP for webhook endpoints.
# Place this directive at the http {} level (outside server blocks) or in a
# separate file included from nginx.conf.
