# HTTP-only edge for «Контракт-чек» behind a front proxy (VPS layout).
# TLS is terminated by the host nginx (deploy/vps/front.conf); this edge only
# forwards to the api service. Same envsubst vars as the TLS template:
# NGINX_SERVER_NAME (expanded by the nginx Docker entrypoint).
# Dynamic DNS resolution: when the API container is recreated it gets a new
# IP. Using a variable with proxy_pass forces nginx to re-resolve `api`
# against Docker's embedded DNS every `valid=` interval instead of caching the
# address at startup.
