# This config:
# 1. Serves the Cathode static files at the root
# 2. Proxies /api/* to WeeChat's relay with WebSocket support
# 3. Handles TLS termination (you must provide your own certs, or use
# certbot: sudo certbot --nginx -d cathode.example.com)
#
# Replace cathode.example.com and cert paths as needed.
