+# addresses (homesrv) — these admin UIs have no auth of their own, so the
+# explicit bind + allow/deny below is what keeps them off the open internet.
+# On a different box, replace both addresses with that box's wg and LAN IPs.
+# Do NOT "fix" a failed bind by reverting to `listen 80` (all interfaces) —
+# that removes the only access control these containers have.
