# Public, auth-less bench UI at https://bench.helexa.ai.
#
# Serves the static SPA from /var/www/bench.helexa.ai (rsynced by
# .gitea/workflows/deploy.yml's deploy-bench-ui job) and reverse-proxies
# /api to the helexa-bench read API on bob over the WireGuard mesh — so
# the browser stays same-origin (no CORS) and the internal API never
# needs to be exposed publicly.
#
# TLS via Let's Encrypt; the cert is obtained/renewed by certbot
# (bootstrapped one-time in script/infra-setup.sh). Mirrors the
# dev.swym.hanzalova.internal vhost convention on this host.
