# Caddy reverse proxy for a GoblinPay till, with automatic HTTPS.
#
# Two names on one host (point both A/AAAA records at this server before
# `docker compose up`, so Caddy can obtain certificates):
#   {$GP_DOMAIN}        -> the GoblinPay checkout pages + REST API (gp-server)
#   relay.{$GP_DOMAIN}  -> the bundled nostr-rs-relay (payers connect here; it
#                          is what the checkout nprofile advertises)
#
# The relay gets its OWN subdomain rather than a path on the main domain so
# there is no path rewriting: nostr-rs-relay serves both the WebSocket relay
# protocol and the NIP-11 relay-info document at the root.
#
# GP_DOMAIN is injected from the environment by docker-compose.
