# Work Package Suite — NGINX site config
#
# Serves the static site and reverse-proxies feedback to a Power Automate
# "When an HTTP request is received" trigger. The browser only ever sees the
# same-origin path /api/feedback, so there is NO CORS and the secret trigger URL
# (with its sig= token) never reaches client code.
#
# Install:
#   1. Copy the project files to the web root (e.g. /var/www/wp-suite).
#   2. Put this file at /etc/nginx/conf.d/wp-suite.conf
#      (or /etc/nginx/sites-available/ + symlink into sites-enabled/).
#   3. Replace server_name, the ssl_certificate paths, and the proxy_pass URL.
#   4. sudo nginx -t && sudo systemctl reload nginx
