# API reverse proxy — frontend is hosted on Vercel.
# Replace YOUR_DOMAIN with api.codestream.npsolver.io (or your API hostname).
#
# Install this HTTP-only config first, start nginx, then run certbot:
#   sudo certbot --nginx -d api.codestream.npsolver.io
# certbot will add HTTPS and the HTTP→HTTPS redirect automatically.
