+# BLS Project Console - Nginx site (for nginx-in-docker)
+#
+# Place this file on SERVER:
+#   /vol1/1000/Docker/nginx/conf.d/bls_project_console.conf
+#
+# Assumptions (based on your Nginx project layout):
+# - Host path /vol1/1000/Docker/nginx/sites is mounted into container as /var/www
+#   so this project static files should be copied to:
+#     /vol1/1000/Docker/nginx/sites/bls_project_console/
+#   and will be served from:
+#     /var/www/bls_project_console/
+# - Backend runs on the HOST at 127.0.0.1:3001.
+#   Nginx container reaches host via host.docker.internal.
+#   On Linux you typically need in nginx docker-compose:
+#     extra_hosts:
+#       - "host.docker.internal:host-gateway"
